I agree with Fharriage: a med change might help with this. It sounds like you're not getting the proper treatment.

But if you're confident your problems are due to schizotypal tendencies, can you bring that up to your therapist at the very least (if you have a therapist at all)? Your therapist might be able to help you pinpoint the cause of your problems, which will allow you to get better treatment.

Good luck!
