Depressed again...

I don't know what's wrong with me. I try to be a nice guy and never be mean and love all my friends and roommates unconditionally. Why do I still get dissed? By people who I thought loved and cared about me. Just when I thought I had something really special, too. It's the same thing every time. Maybe I should be a macho, woman degrading asshole with an atitude. Maybe that would get me farther than I am now.
