This is for kyrz, too:

I wish I had a great solution to this, but now that you've both further explained your situation--yes, I understand now that you are both right and both need new friends. The kind that only show up when they need something out of you are obviously not the helpful kind. I hope somebody has some answers to this one for you better than I can give--in the meanwhile, I empathize, because I know how tough life can be when you're all alone.
