I'm goign to give a little back story here to see if anyone else can shed some light on the situation. Me and my best friend were having a sort of play arguement on Facebook. We had both agreed beforehand that nothing was off-limits to post so as to make it seem more convincing. It was going pretty well. We were both on msn telling eachother what to say and it was really funny. Then he tells me that his friend is writing an angry post on my wall. I didn't mind this since I've met her before and she can take a joke, so I figured we'd tell her afterwards. So she posts about three fairly vicious comments and I decide that it's gone far enough and if I don't tell her what's going on then she'll end up looking like a fool when she finally realises that we were just kidding, and I quite like her so I don't want that to happen. So I go ahead and send her a private mail saying "We're just kidding. Thanks for the comments, they made it look way more convincing. :L". I'm about to log off when I see that she's replied : "He wasn't kidding, 'sweetheart'. And neither was I." I figure that my friend, let's call him Jeff, was just overdoing it and that he's still messing with her. I tell her that it was my idea, that he's kidding etc, until the point where she shows me various things he's said to her. Jeff was telling her stuff about my anorexia, calling me an attention w****, saying that he really thought I was annoying and was just humouring me. I asked Jeff, and he went offline. I already don't tell him some of my deeper, more corrosive secrets, but knowing that he said this... I trusted Jeff more than anyone, and I feel so used, so stupid, and I don't have any other friends to talk about it to. I'm so reserved with what I say, and then the only person I talk to about my cutting, the way I feel about myself, goes and tells someone else everything. I'm so lost. What do I do?
