So to summarize, because your language is confusing me, you are:

1. Schizophrenic, but choose to self-diagnose as autistic.
2. Do not trust anyone, including your doctor.
3. Looking for someone to trust and converse with (and possibly have sex with, but I take it you mean 'intellectual fuckbuddy' as opposed to 'intellectual masturbation')

You may scare people off, as your symptoms of schizophrenia could be more noticeable to other people than you may realize. Please talk to your doctor and ask him to change your medication if it doesn't work.
If you don't want to do that, than learning to recognize and control your words and actions would be a good first step. Avoid talking about guns and death. For some reasons (and honestly I don't completely understand why myself) these types of topics can creep people out.
