Nummy, thanks for your post. No, she hasn't actually done anything to me. The problem, however, is that when she says she is busy to talk or make plans, I start crying. (Not in front of her of course). So I need to protect myself against this no matter what my reason for being upset. It really hurt today when she said I needed to get busier and that she could not fill up the "void" I have.
When we were best friends before my mania, we talked constantly and did everything together. I had almost no other active friends. When she broke it off with me I went out and developed a new set of friends. I still am very aggressive about seeing and keeping up with all of these other friends. So it's not as though I have nothing to do. Plus, I am starting to exercise and do all sorts of things. I went out on disability a few months ago and have had to work hard to fill up my days in a productive manner that does not trigger me to feel overwhelmed.

I really like how you said that friends are there when you need them, not just in bits and pieces.
