Seems like a couple of things going on here: one, how you are feeling, and two, how to make real friends. First, if you are willing to try reading a "self-help" book to feel better then I would recommend the book Feeling Good by David Burns. He basically identifies simple ways to get passed typical thoughts we all have that cause us to feel bad so we can start feeling better. It helped me a lot when I needed it and I've never really gone back to feeling bad the way I used to. I used to talk myself into feeling bad but now that I'm aware of how I was doing that, I know how to avoid it. If you are not into self-help books then just forget it.

Second, making "real" friends is more complicated because there is no checklist to know if someone fits in the real friend category. Each friend is unique and you kinda have to take them as they are. Think about this, everyone in the world is just trying to figure things out like everyone else. No one but God (you said you're religious) really knows what life is all about--even your parents. The saddest and loneliest person, and the person who seems to have it all together, each one is just doing their best to make it in this world. We are all the same in that way. Knowing that everyone struggles helps me realize that everyone needs "real" friends just as bad as I do.

That leads me to some actions that I take that help me make friends (some friends are closer than others). I try to treat people kindly knowing that they are struggling in the world too. Even people who are annoying or I don't really like that much. I know they have troubles too so I try to be nice, smile, hold the door for them, pick up something they dropped, whatever. When you're kind to other people that way, it can actually make you feel better about yourself as a human being--especially if you are NOT expecting to get anything in return. It doesn't mean these people are going to be your friend. But you would be surprised about one thing. Other people will notice that you are a kind person and most people want to be friends with kind people. Don't you? Also, when you are happy with yourself for being kind, it can actually make you feel better about yourself. People will notice that too, that you are happy with the kind person your are. After that, friendship depends on how much time you spend with each other talking, eating meals, playing games, whatever. If you don't spend time doing things together, it is not possible to become real friends. The more time you spend together doing things, the better friends you will be.

I'm glad you wrote this. Obviously you are not suffering alone. We are all just trying to make it in this world. It's nice that we can help each other out a little bit.

First off, from a fellow transfer student, Welcome to UMD!

You'll be fine with your preparation so far. A lot of people go into 131 with little or no programming experience and do fine, and you'll already have a leg up on them.
I would download eclipse at http://www.eclipse.org and start looking through the textbook from the beginning.
Here is the class web pages list for the CS department: https://www.cs.umd.edu/class/
You can find course webpages for nearly every course offered there. Many have lecture slides and projects that you can look through and work on. Many will possibly be reused for your class. Some (NOT all) are password protected, just skip them.

The best thing about Java (IMHO) is the publicly available documentation. C has next to none, Ruby's is always missing stuff or has incorrect info. The java documentation is really well-done though.
If you haven't used Java before, the javadoc for Java SE 7 can be found here: http://docs.oracle.com/javase/7/docs/api/
Get used to navigating it. The different "packages" are easy to navigate in the top left frame. In my 131 class I think the only ones we used were in java.lang and java.util.

For any math reqs you still need, I'd advise learning all the material beforehand, the math dept. is notorious for having some TAs that are cruel graders.

A note on books...I've taken 131/132/216/250/330/351, and not once has the "required" book actually been needed in the class. The 132 book I used http://www.amazon.com/Data-Structures-Abstraction-Design-Using/dp/0470128704/ref=sr_1_4?s=books&ie=UTF8&qid=1374108009&sr=1-4&keywords=data+structures was a useful reference to have for Java, but It mostly covers data structures which aren't used as much in 131. 216's Pointers on C was fairly useful as well.
The Association for Women in Computing group on campus does book sales, w/ textbooks for $5-$10 each. Never anything assigned for a class, but it's a good place to get a cheap book for a language/topic you're interested in or as a supplement.

If you're interested in Artificial Intelligence and have room on your schedule, I highly recommend taking CMSC289I w/ Dr. Reggia. There's no programming experience required and it's an excellent overview of AI concepts.

Well, that's all I've got.

Since you're starting a Java programming course in two weeks, I'd recommend this one.

It's one of the books I own. Admittedly this is not the book I would normally give to a complete novice in programming, but I think it's the best for the situation. It's a pretty fat book and full of knowledge, but it assumes the reader has some sort of technical background. It doesn't do much to help you visualize it in other ways. However it gets straight to the point, is fairly clear, and is ordered well. If you can understand the material in the first 3 chapters before the start of your class I think you will be very well off.

Kant's Critique of Pure Reason (CPR) gets taught very rarely in this department. The department recognizes the need to have a course on Kant's CPR (or, alternatively, on Kant's shorter version of the CPR, his "Prolegomena to Any Future Metaphysics"), but the Maryland philosophy department (a) doesn't have many faculty who work on the history of philosophy, and (b) those faculty who do work in the history of philosophy either do work on ancient philosophy (Rachel Singpurwalla, Quinn Harr, Kelsey Gipe) or on Spinoza and other historical Jewish philosophers (Charles Manekin).

Sam Kerstein of course does work on historical Kant, but Sam's focus and interests in Kant is fairly exclusively directed towards Kant's moral philosophy. This is why Sam teaches a 400-level class on Kant's Groundwork every other year or so.

The upshot is that I am the first person to teach a course on Kant's CPR at this department in many years (6+). I'll probably teach the course again either next school year or, if not next year, then the following year. Unfortunately, that sounds like it might be too late for you (from what you've said, it sounds like you graduate this year).

Fortunately, I would argue that it is better for you to have taken a class on Kant's Groundwork before you graduate than Kant's CPR. Kant's ethics is more important to contemporary philosophy than his epistemology and metaphysics. That being said, I do hope you decide to give the CPR a read on your own time someday or at least read a secondary source on Kant that covers the important content from the CPR in detail.

If you decide to read Kant's CPR on your own, let me recommend some resources. First, I'd suggest you watch the following two videos about Hume and the following three videos on Kant as background (although, unfortunately there isn't a video connecting Kant to Hume through how Kant's CPR is in large part a response to Hume's skepticism):

• Hume's Skepticism 1 https://www.youtube.com/watch?v=-QpUrSn3cWU
  
• Hume's Skepticism 2 https://www.youtube.com/watch?v=dPlNsyXl-0c
  
• Kant's CPR 1 https://www.youtube.com/watch?v=vZtQXteAE-w
  
• Kant's CPR 2 https://www.youtube.com/watch?v=vQnG0fyEr_w
  
• Kant's CPR 3 https://www.youtube.com/watch?v=vQnG0fyEr_w
  
  You might want to also read one general secondary source on Kant's whole philosophical system before the CPR. Here are a few suggestions to pick one from - all accessible to a upper-level undergraduate student or graduate student. I am not sure which one would be best to recommend:
  
  
• Paul Guyer's Kant https://www.amazon.com/Kant-Routledge-Philosophers-Paul-Guyer/dp/0415843456/ref=sr_1_22?s=books&ie=UTF8&qid=1504276067&sr=1-22&keywords=kant
  
• Roger Scruton's Kant: A Very Short Introduction https://www.amazon.com/Kant-Short-Introduction-Roger-Scruton/dp/0192801996/ref=sr_1_4?s=books&ie=UTF8&qid=1504276050&sr=1-4&keywords=kant
  
• Allen Wood's Kant https://www.amazon.com/Kant-Allen-W-Wood/dp/0631232826/ref=sr_1_27?s=books&ie=UTF8&qid=1504276277&sr=1-27&keywords=kant
  
  There are also several specific secondary sources aimed at upper-level undergraduates and graduate students that specifically cover Kant's CPR. One of these might be useful to have besides you as you read the CPR for those times you get lost:
  
  
• https://www.amazon.com/Routledge-Philosophy-GuideBook-Critique-GuideBooks/dp/041511909X/ref=sr_1_12?s=books&ie=UTF8&qid=1504276632&sr=1-12&keywords=kant+critique+of+pure+reason

• https://www.amazon.com/Accessing-Kant-Relaxed-Introduction-Critique/dp/0199275823/ref=pd_sim_14_11?_encoding=UTF8&psc=1&refRID=AZ7XQ4TK2FHQPD91321D

If you're serious about going into computer science, I would strongly recommend taking a mathematics course, just to get you thinking logically. (You're going to end up taking 250, but still, it's incredibly helpful)

I'm not going to mention the coursework partly because /u/lordlicorice does a good job already and partly because I'm also a freshman like you, and I can't really advise anything from experience. I'd just suggest reading Introduction to Algorithms, which is a pretty well-known book to get started. I've also picked up Cracking the Coding Interview, just to help with some tech internships I want to get into. (My professor implied sometime back that you should have at least 330 before considering internships, but some of my friends have done some even before 216)

Key thing to understanding OCaml and functional programming is Lambda Calculus, which I'm pretty sure you will cover in 330.

As for 351, it's really hard to say what to do to prepare as it's less concrete, as what helped me the most was discussing the concepts and going over the homework with my tutor (so find a study group if you can). All I can do is give you some playlists. Also I used "Intoduction to Algorithms - A Creative Approach, by Udi Manber" when I took 351. I mean, I think CLRS is a great book, but I think it's a bit overkill for 351. I mainly used it in 451. I mean, stuff like maximum bipartite matching and maximum cut is in there, but you won't encounter those in 351, only in 451.

If you want to make a videogame, you could use what you know from Java and make a game with libGDX, or join the Game Developers Club and work on a team to make a game. Games are good projects to show to possible employers.

A lot of internships at small local companies wont have super crazy tech interviews, but I would suggest getting Cracking the Coding Interview if you want to see some example questions to prepare.

Also, I have never put my GPA on my resume, and I have done pretty well for myself. If your GPA drops under 3, just drop it from your resume and only give it if a possible employer asks.

your tripping out, just buy the 2nd edition from amazon for like 15$ and save some money and you'll be fine, chemistry hasn't changed a whole lot in the past decade.

Like Airth said there's no required book across all sections but some professors may recommend one book or another.

Professor Reinhardt recommended this text for 131 and 132 (I'm assuming that's what you're going into right now): http://www.amazon.com/Java-Foundations-Edition-John-Lewis/dp/0133370461

Googling can find you a pdf I think.

When I took the class 3 years ago we used Boyce and DiPrima's Elementary Differential Equations. I thought it was a great book since I ended up skipping most of the lectures and teaching the material to myself.

Why are you worried about not being able to handle your classes? It sounds like based on how you did first semester and the fact that you got into the school, you're capable of doing well in those classes.

A lot of anxiety comes from negative self-talk and letting your fears spiral out of control. If you're constantly telling yourself that you can't do it, you'll start believing yourself. If you let a small fear("my classes next semester are challenging") keep growing("my classes next semester are really hard") into something that's a real problem("I won't be able to handle my classes next semester").

This book is a good resource for understanding anxiety and how to change your mental habits to be healthier

Feel free to PM if you have questions or need to talk

That's not the standard 310 textbook. This is. Also, in 310 you go over the first 3 chapters of the 410 book. I'm not disagreeing with your comment otherwise though.

Why not just buy an electric scooter at that cost?

This is 351's bible.

For 330, just read last semester's slides.

Practically Speaking https://www.amazon.com/dp/0190457325/ref=cm_sw_r_cp_api_i_5FczDbN4G534W

Just learn C. There are tutorials all over the place, or you can buy http://www.amazon.com/The-Programming-Language-Brian-Kernighan/dp/0131103628

Here ya go. K and r for the authors' last initials. http://www.amazon.com/gp/aw/d/0131103628?pc_redir=1408940727&robot_redir=1

Ehhh, there's no secret there. You can pick up a classic textbook with knowledge that a 1935 researcher would kill for easily. Heck, wikipedia has some really amazing nuclear resources. Now, actually building things, now that's tricky.
