That sounds like a pretty rough situation to deal with. I myself have come to the conclusion that my desire to be alone isn't really healthy simply because I'm not doing it for the sake of being alone, but because I have a disorted perception of people, places, things. Distorted reality.
I'm willing to bet that you realize the things that go through your mind are irrational. If you don't take control of your mind you will spiral out into obscurity. You have the power to reject or accept your own perceptions. If you know something running through your mind is strange and unhealthy do something about it. Take control.
This is how I'm healing myself, and its working. I'm taking control of my mind. I'm not going to allow it to destroy the quality of my life. I'm not making any excuses for myself because I know that I'm totally able of having a healthy and happy life. So can you. I think that even some schizophrenics could have more control over themselves. I don't feel sorry for all of them. Some are just playing an eloborate game and being very childish.
