Don't stop the meds kiddo. Thats the worst thing you could do.
If you enjoy learning then further education is the way to go. You can immerse yourself in learning while dealing with your problems but if learning causes you only more stress and confusion then its not the way to go!
It's up to you to decide but if you think that learning new things will help then go to college....but if you think that getting stuck into some physical labour will take your mind off it for a while than do that!!
As long as your happy doing what your doing day to day, then you can deal with your psychosis along with it
PS dont worry....your not the only one ok
