When I'm Hurt

They say that I gossip about them in front my entire class; they say that I'm not being honest to them; they say that I take everything too serious that I always get mad easily; they say that I'm frustrating them; they say that I'm annoying, over-sensitive, and selfish.
I try to explain, I try to keep our friendship so badly, but nothing works out. I give up eventually, because no matter how much they dislike me now, I can't do anything with that, and no matter how much harder I try, all I can get is no reply.
Mom says that I really care about them too much that I always think about them first and hurt myself. I agree.
I say that friendship is just like love relationship. When you love someone so much, you will hurt yourself; when you care about a friend  so much, you will be wounded.
If friends hurt you and don't realize it, then they are not friends anymore. I think that to myself. Just become a little bit selfish, I'll let myself happy first. Therefore, it's the right time to forget about the friends, and care about myself more than care about anyone else. Maybe they mean to hurt me? Then I'll let them see that I'm not hurt at all! And one day, they'll realize that I'm way much better than them, and by that time, they won't be able to wait to bow down and get out.
Now I'm not hurt anymore. The wound becomes a motivation. I'll do better than they do, so why bother!
