;_; PLZ make it stop...

So, I'm on Chatango (http://tamachanlol.chatango.com), and I was having a conversation with my friend Stella-Bell. She went offline, and I didn't bother to log out. So I'm sitting there, and this guy starts talking to me (well, a lot of people did, but he's the only one I have a problem with). So, he starts in about his sad horrible life. I'm generally good at listening, but it's been over an hour now....

AND HE'S STILL GOING ON AND ON!

He's freaking depressing me, which is really hard to do. And I don't know what to say to make him stop. I don't want to be rude or mean, and I know I should listen, but he just WON'T STOP! ;_; Why, why oh why!? All this stuff about his friends' babies dying and his sister getting raped and his friends having miscarriages! I don't think I can stand another minute. I kind of want to block him, but I can't because I'm too much of a doormat.

I never mind listening to people I care about's problems, even if it takes all day for them to tell me about them. But I've never, ever met this guy before. I guess I'll keep listening and see if I can cheer him up.

I hate to be mean, but I just want him to stop! He's a really nice guy and everything, but ouch.
