Depressed teen has no one to talk to

Hi, I've been really sad lately. I think I'm depressed. I try to be happy, but I honestly believe there is no good in this world. I see no point in living. My school sucks, its a long story. I had a group of friends but I left them because there were high maintenance and selfish. now I have one friend, maybe....My school makes me depressed in sociology we had to watch a bunch of video's about the death penalty and about people getting killed and raped, and it makes me want to cry. we have to learn about awful stuff, and I get so freaked out and disturbed by it, while everyone else is fine. people in my school stare and me. I don't know why, when I'm walking down the hall, they just stare and stare, with this look. and I don't just get it from people at school, I went to this convention and everyone stared at me the same way!!! it was a freaking convention, so everyone was dressed up in crazy costumes, and they stared at me like I was the freak. Everyone in my school is sexist, I'm really sick of all the "stay in the kitchen" jokes. I try to find some reason to be happy being a girl, but I can't. whenever I try and find some women pride forums, all the comments are really mean and offensive. I hate people. everyone thinks their better than me, I always get looked down on. and now my brother hangs out with my old group of friends so I still have to tolerate them and listen to him gush about them.

I've been sad for several months and see no hope for the future, I just needed to vent.
