Hello, I am Zach and I am 18 years old. 2 years ago I suffered a traumatic experience that changed me completlely. I had brain cancer, and now it seems my friends are tired of seeing me sad and not having fun. They think I am a downer and think that I should not be sad anymore. But it is really hard for me to have fun when I am still having troubles. But I feel that they are not my friends anymore, they simply don't understand. Hell I don't even understand why I have the problems I do. I have a hard time thinking of things to say in social situations now and that triggers emotions, and then everything gets out of wack. I just want to know what i should do. Maybe I should just give it time and try to talk to them again one day when all this is behind me. Or maybe never again.
