I know I haven't posted in a while, but thank you everyone who gave me advice. After this weekend, I basically decided that while I still want to hang out with X, it's going to have to be the two of us (or at least a large group if Y is there). I never flat-out said that to X, but I think she kind of knows that's how I feel.
It's really hard doing this, but I'm sure things will get easier with time no matter how everything ends up. I was talking with one of my sisters today, and I realized that the only reason I'm upset by all this is because when I just went along with everything, X and I were close as ever, but as soon as I started getting fed up with it all and showing my annoyance, our friendship started suffering. While I couldn't care less if I never spoke to Y again, the fact that she was what at least part of what made X and I less close makes me really mad. It'd be one thing if we just grew apart, but all the problems Y caused make me wonder if there was something I could've done earlier to prevent all this. Well, that and I realize that with all the graduating and having no job stress that I'm under, I'm not the most fun person to go out with, but considering X had a few months there where she was depressed, living at home, and jobless and I still called to make sure she was ok and to drag her out, she of all people should understand where I'm coming from, but apparently that's not the case.
Hopefully X and I will still be close after all this - most people seem to think she'll just get sick of Y's psycho behavior after a while and we'll end up ok again, but we'll see.
I'm sorry, I wrote all this about 30 minutes ago and can't even think of what else I was going to say - we heard a loud bang followed by a ton of sirens and just found out that one of the life flight helicoptors crashed into the side of one of the towers at the hospital a block away and exploded. Needless to say, I feel kind of dumb bitching about a few friends of mine at a time like this. If I remember what I was going to say at all, I'll be sure to post it later - but thanks again and keep the advice coming, and please keep those involved in the accident in your prayers...we won't find out how bad it is till morning.
