I just want every thing to end!?

I think i may be depressed. I want to tell someone but I don't think they will beleve me. I am only 12. I have tons of friends. I had 2 boyfriends this year and I broke up with both of them. I cry so much when I am alone that it isn't even funny. I cry myself to sleep every night. I just don't know what is wrong. I don't cut myself or do drugs or sleep with guys or anything like that. I do sometimes scratch or bite myself. I am not emo or anything. I am the biggest prep ever. I listen to country and stuff. I play sports and I am very social.... I just don't get this.
Help Please!

Hi, I am now 32 years old and I do understand how you feel. I know that young people like yourself have more stress than people my age did when we were young like you. When I was sad as a young person I used to write in a journal everyday. Talking in it like I was talking to someone who didn't think I was silly for thinking or feeling different things. I also, when I was sad, made sure to write down things I was happy I had in my life, like sports, friends, pets and things like that. Sometimes when you are hurting a lot it is easy to forget all the neat stuff around you. I want to say you sound like a very smart young lady who is just learning how to deal with lots of new emotions. If you can't talk to someone, try writing your thoughts down, good and bad. Sometimes just getting them out of your head and onto paper, or a personal blog, helps you sort through them and make them not hurt so much.
