Hating Your Life?

Okay so I'm dealing with a situation here. My friend hates her life... why? I'm not sure, I'm worried though. Hating your life can lead to suicide... but you know that makes me feel bad when she says that... that her life sucks and she hates it all because I try my best to make it worth living for her... your friends should be able to pull you through. Everyone goes through this even if you don't think so. Stop being sad :( I'm just, scared. Stop please :((
