Friend drama, and I get in the middle constantly!?

I went off to college expecting all the annoying high school **** to be finally gone (I HATE drama). I get to college, and I'm pretty freindly with everyone, but this means that people come to me with problems, and ***** about thier freinds who I also happen to be freinds with. I hate it. They expect me to agree with them all the time, but I can't because the other person is my friend as well! I am really tired of this. College is about finding yourself, experimentation, making new friends, and new experiences! I am tired of trying to mature and enjoy my college experience when my freinds are constantly pissy and complaining about each other. Any advice on how to stay out of it? I am normally not involved at all, but any other way I can get them to suck it up and grow up? Thanks, I've been stewing about this for a couple weeks now.
