So I've struggled with BPD since I was a kid. I'm now 22, and have had all the volatile relationships, mood swings, idealization and devaluation in past relationships, impulsiveness, etc.

A few weeks ago my mom asked me if I was gay. I asked her what she meant by that, and apparently my inability to be in a relationship somehow convinced her that I was into other men. I kind of laughed it off and went to my room, and then I got to thinking. How in the hell did she come to that conclusion? She asks me daily why I don't go out, and thinks I'm a hermit, but she doesn't see that I may have something wrong. I also know that if I just come out with it and tell her I have a disorder that she'll laugh it off and tell me to get real. 

I'm not looking for sympathy or any condolences, but if anyone had any advice or coping mechanisms other than booze and cigarettes, I'd love to hear them.
