Wow, I can really relate to some people here. I guess I'm not alone. Anyways, I felt I'd bump this thread instead of creating a new one to mention something that occurred to me lately.
I think that mental conditions/complexes are often as much a result of circumstances as they are of a chemical imbalance. I have anxiety, paranoia, and depression. The root cause may be biological, but things that have happened to me, and how I have been treated, have also contributed greatly. I have been treated like shit in my professional life (getting lied about and fired, etc.), been treated like shit by women, and been stabbed in the back and fucked over by friends. I think people are evil, and think anyone would love to tear me down to build themselves up. It's part of human nature. Living in a hostile world contributes greatly to my anxiety, because I feel I always have to be on guard. It has also made me oversensitive. Recently I went off on my roommate and threatened to kick his ass just because he made a joke implying I was uncoordinated when we were playing beer pong. He said I take things way too personally, and I think he may be right. But being treated like shit all my life is partially what has made me this way. Being treated like shit is also a big factor in my depression, and logically my paranoia and misanthropy as well.
