you have autism
yes but I believe it's a different type than aspergers (I don't act like the author describes themselves as acting; they say they always did things just to see what would happen on a regular basis, I have trouble focusing on anything and just generally act weird.)
Someone said "You're trying to pretend what you have isn't a disorder" but I'm not, it is a disorder, but I don't need a book of life advice like that, really. It's mostly stuff like "Hey, don't play videogames 24/7. Don't stress over grades too much. Don't pick too many hard classes." Stuff that might not be obvious to someone with a more serious form of autism but I already was thinking about that sort of thing. I don't panic about grades, I keep an eye on them and do something when they start looking bad. I did try to pick classes that would be easy or interesting and not hard classes. I do other things than just videogames, though I do use the computer "too much" (That's like saying I work on crafts too much, or read too much. Just because it's on the computer doesn't mean it's worse than any other hobby.)
