MI has made it more difficult to form friendships and relationships with others. Luckily my wife is schizoaffective so we have quite a meeting of the minds so to speak! It's helpful to have someone in your life who's had to deal with the same kind of situations as you.
As far as dissociative disorder I just don't talk much about it. I'm lucky I don't have DID but I still have blank outs and other symptoms. I have DDD disorder.
As far as suspiciousness goes I hope for the best and prepare for the worst... that way I'm rarely surprised. I hope I've answered some of your questions.
