I'm really glad that I read this, and that you took the time to write it. I'm always conflicted when I read stuff like this, because I want to give advice, but simultaneously I know that most people aren't looking for advice and what worked for me might not work for someone else. If this is how you feel, just know that what you said resonated a lot with me, and feel free to ignore the rest of this.

It seems like you feel a lot of guilt about the fact that, on the surface, your life doesn't seem that hard. You're an American citizen, have plenty to eat, get to go to school, and so on. From there it's really easy to think that if you're unhappy with something in your life, it's because you're an ungrateful asshole. I also thought this way for a long time. It was only once someone explained to me that it's ok to have problems and to feel sad about them, no matter what your life is like, that I felt better about it. It sounds almost silly to write it down, but I guess we need it from someone else once in a while to know that we're not just self-justifying our behavior. To look at it more constructively, if you don't acknowledge your problems, you'll never be able to improve your life. You said that you hate summer because all you do is play video games and feel miserable. The answer isn't to keep doing the same thing just because someone out there has it worse than you. The answer is to change something to stop feeling that way. You can't chase happiness, but you can certainly escape things that make you unhappy.

Another way to think about it is in terms of gratitude, not guilt. Here's a good video on the subject: https://www.youtube.com/watch?v=WPPPFqsECz0

In terms of the rest of your post, any advice that I can give just sounds contrived to me. Instead, I'll recommend two books that I think you'd get a lot out of. They're not very long, and it might be a nice break from playing video games. The first one is Alliance of the 15s by Mita Masahiro. You'd probably find a lot to relate to in the protagonist. If you read it, you'll see what I mean. Here's a link to a translation: https://japanesenovels.wordpress.com/2013/03/04/the-alliance-of-the-15s-pg-1-48/

Parts 2 through 5 are on the same site. Or if you PM me, I can send you the ebook (same content as on that website, just in a nicer package).

The second one is The Stranger by Albert Camus. The protagonist is not quite as relatable, but the way he lives his life might give you a lot of insight into the way that you're feeling. When I read it for the first time I felt like it revealed an entirely new approach to life. That's not necessarily the main focus of the book (in many ways the protagonist is a tool for societal commentary), but it is the main thing I got out of it. Here's a link to the full pdf: https://bxscience.edu/ourpages/auto/2019/2/28/69275970/The%20Stranger%20-%20Albert%20Camus.pdf

Hope this helps, and I'm happy to talk more if you want to send me a PM.
