Oh, I know the feeling all to well. I even had "friends" from high school call me up out of the blue just because they needed someone to talk too and they decided since I was so understanding back then, I would be now.
I don't recall myself being understanding in high school but whatever, I talked to 'em anyway. Told them things they didn't want to hear and it pissed them off and made them hate me, but eh.
Even a few months ago I just cut ties with someone who was using me for emotional support when they wouldn't do anything to help themselves get out of any situation. I had to dig them out. After my emotions were run through the dirt and mud I had enough.
Lashed out in a bad way though, but at least I'm free from that crap.
Anyway, I hug you
and say if we lived anywhere remotely close together I'd call you up to hang out, order a pizza, play some left 4 dead
