Tom,
I'm so glad to hear that you are learning so much. It makes it so worthwhile for you to be there. Sometimes I wish I could just pick up and go to rehab, but as the single mum of three (or should I say divorced mum of three?) with no backup, I can't. I think you're fortunate to have this opportunity and I'm soooo glad you're getting as much as you can out of it.
I hope it gets easier for you to express your emotional self. If you can, try to relax. It's OK to be honest. You won't sound stupid. The people there aren't there to judge or hurt you more, they're there to help in any way they can. Sometimes it helps you heal if you can just get it out.
Thinking of you,
CS
