I always try to make people happy

When someone's upset, crying, posting on their blog about their life or whatever I always try and do something to make them feel better. I can't stand to see friends like that, because I know what it's like to be in their situation, so I help them. I wish someone would do the same to me when I'm upset too though, but no one really bothers. My friends do care to an extent but just not enough to talk to me about it and try to make me feel alright you know?
