I find it hard to make friends because of the anxiety, but I'm sure I'm not that much better at it when I'm depressed. I'm missing a friend's birthday party because she has a lot of other friends and I'm just not good at handling lots of people. I should contact her and go out to lunch or something, but I'm afraid of leaving my house even with my husband in tow. These illnesses suck. All I can do is talk to her through Facebook. I think it's also hard because we don't have a whole lot in common (we met through our kids' activities).
Anyway, I'm sorry that you're having a hard time, but you're not alone.
