That is about where I was about 4 years ago except I was about a semester into my first year. I thought it was bad then but it got worse. Anyways If college is causing you that much stress and you feel you'd be able to better handle technical school I would do it.

I understand not wanting to lose your parents support but I've learned, acting on that fear does much more harm than good a lot of times especially if it involves pushing yourself too hard.

Other then that you could try taking a break and resuming, or maybe you could try a lighter class load. Or you could go to a community college part time, I think you can typically still get loans for that I know I did unfortunately it didn't work out because of great things like depression, PTSD and anxiety. I supposedly have Aspergers Syndrome as well(its likely the reason I always felt quite a bit different from other people either that or they are wrong about personality disorders only developing in late teens and adulthood in all cases). However, I don't think that really interfered much with college grade wise, though it could be a factor in some ways like the social aspects and such.

I wasn't exactly an A + student in elementary/middle/highschool or even college but I did pretty good, I was pushing myself so hard just to get it over with so yeah my family did not really expect things to go the way they have for me and so now I am kinda stuck depending on people who don't understand me at all in order to survive at least till I get on SSI.

Anyways it sounds like quite a bit more than being 'sad' and there are people who understand that, its too bad you seem to have more of the ones that don't in your life. Do you by any chance have any on campus counseling or anything? not like class advising or whatever but like to talk about problems or mental issues some colleges offer those kinds of services free or as part of the tuition costs and it might be helpful.
