I'm sorry you had a tough time at group therapy. How many times have you been? Sometimes it takes time to get comfortable in the group. Why don't you stick out your hand and start introducing yourself. You're not alone. When I was IP once and OP twice it was like them pulling teeth to get me to participate. I'm just shy and reserved.
I'm glad you posted. I've been worried about you. I'm here if you need to talk.
