A very good question. As things are now in mental health, I'm not sure I have any good answers. Just try to look at what your experiences are, and try to examine them, try to understand what they mean, treat them seriously, but don't try to attribute them to external conspiracies. I think they may be related to your experience in the past, rather than what is going on now. I mean, there are reasons in one's past experience to distrust people, but that doesn't mean that the same things are going on now -- or that you are the same now.

It would be best (!) if you could find someone in the mental health system to help you examine respectfully what your experiences mean, but good luck in that. I find a lot of disrespect in the mental health "system".
