If you're not enjoying what you're doing then drop out of college if you feel that's the right decision. You need to feel comfortable where you feel you belong. I've got Hydrocephalus and might be autistic myself, and I loved and thrived in the school environment. I didn't do that great in college (B,C and D for my core subjects), but I managed to get into university and obtain a degree doing what I love doing. If you're struggling on your course I think you should try to seek advice and guidance from teachers and friends/confidantes, or you should find a job and move on with your life. I think the stress you're enduring comes from feeling trapped, I've been in that predicament before-but life will move forward and you should make the choice that's right for you. Don't feel the pressure and try to gain control of how you feel-I know it's hard when you're young to feel in control of much, but if you know what you want and you go towards that then you'll find the direction you need and happiness should await you.
