Talking to my doctor about my depression?

wow..........Okay I'm the same age and I have felt the same way. People say that these are supposed to be the best years of you're life, but sometimes that's just not true. I would start by telling your doctor everything you just posted. I don't think there's anything wrong with you that can't be fixed. I'm even starting to come out of my "everyone and everything sucks phase". You're not weak, some people just don't have it as easy as others, but you're young and there's hope for you yet. Good luck.
