Have you had your interests and/or aptitudes tested? It sounds like you do not know yourself very well, haven't figured out what really is what you want to do. It could be you would be better working more on your own (instead of with others), in different surroundings.

Maybe go see a testing psychologist or see if your former college/university (if it is nearby) has such tests for alumni as well as current students, etc.

If you feel you actually have misleading thoughts, are seriously paranoid, etc., then I would go see your medical doctor, get a complete physical and then maybe a referral to a psychiatrist and see if maybe cognitive or dialectical behavior therapy might help.
