Sucks when you have someone like that who is family and you're stuck having to deal with them.

I have a sister who's never had any goals or ambition in life, who's just drifted along from one bad choice to another, and who always blames others for what happens as a result of that.

And constantly complains about every little thing, non-stop. Just being around her for 10 minutes totally destroys my mood. If we didn't have the same mom, I'd want nothing at all to do with her.

Some great advice in this thread though -- I think exercise is a good one, I always feel a lot better when I go to the gym regularly, and when I take long hikes in nature
