Don't know how to help out my friend...

Keep doing what you're doing. Keep trying to talk to her and help. Get her out of the house and show her a good time.

I also have that problem except she moved she i cant exactly comfort her. I just have to try and do it from a distance.

I hope I help at least a little. It's a very hard situation.

Well, usually when a person doesn't want to talk it's because they're lost within themselves. Thinking things over, and trying to figure out everything, getting themselves really stressed and tired. This 'tired' affects all aspects, the physical, emotional and mental fatigue. So I don't know if you will get through to her any time soon, or atleast you won't with just simple words. But that doesnt matter, if you keep trying atleast she knows thatyou're there if she does infact need to start talking again. She'll know that you care. If you stop talking to her, she might start thinking thatyou've given up on her....

If for some reason, you keep talking to her and she seems like she's only getting annoyed, then maybe just cool it down a knotch - but let her know your always there for her of course.

I can see why shelley would say go out and show her a good time, but it isn't always that easy. I mean she might not answer to your invitations either...
I would love to keep helping, but it's really hard to do much if I don't know the person. Most problems are figured out according to people and their personality type... So really all I can do is wish you all the luck in the world. Don't give up on her. Sorry I couldn't be of more help.
