What should I do?.. (Long story)?

I went through the same thing last year as a freshman. The boy I love got into a relationship with my best friend, who started to hate me for no reason. Every day I would see him and die a little. It was horrible. It gets better, everything does. For awhile people were so mean to me that I almost switched schools. The most impotent thing is to try to focus on what you do have. Sports, grades, anything. It was so hard, I almost killed myself. Im still in love with him and hurts everyday, but life goes on:) good luck!
