Friendships tested

It really surprises me some people who claim that they are my "friend". Why is it when they are sad I seem to be the one who comforts them and make them feel better. I haven't been feeling good this whole week I've been depressed... i finally decided I would try to go to class tonight. As I drove on the fwy towards my normal route I changed my mind and i didn't want to go. I didn't want people asking me what happened. I have learned a lot these past couple days there are only few friends you can really count on when you are down those are the ones you should keep closest to your heart.
