Why do families suck?

I just bawled my eyes out after a One Tree HIll episode.  It hurts for me to watch daughters getting along with their moms and having a close relationship.  I really want that in my life but I know it is never going to happen.  I can't even go home from college because then I have to remember how bad it really is.  It is much easier to get by thinking that maybe it isn't that bad.  I don't fight with my mom that much when I only talk to her once a week over the phone.  I wish I had a home left.  The dorm is my home now but its not even permanent.  I really just want to move into my apartment for next year.  Then I can have a real home again.  I love that my friends are my family but it hurts sometimes to know that they are closer to me than anyone in my real family.  I feel bad for not being there for my dad.  I love him and he deserves better than our shitty family situation.  I really hope he is happy.
