I need help learning social skills. I'm like...hopeless. I humiliate myself all the time.

Does anyone have any recommendations? Activities? Books? And so on? Or advice?

Part of my problem is being socially phobic and introverted. At work I don't know how to interact with my co-workers. What's okay and what isn't okay. Or even how to participate in group conversations. Most of the time I just focus on my work, and only talk to a few of them that have been winning my trust.

After my psychotic break, I was basically a shut in. I barely socialized for 5 years. So I'm really, really, awkward. And I'm getting tired of embarrassing myself all the time and having painful friendships because I don't understand relationship dynamics.
