Thanks so much for the information, everyone!
I just got back from my first day and it was basically a bit of all of what you've all said combined.

I was a bit taken back by the group therapy, I wasn't too sure what to expect, but now I know. I'll probably struggle the most with group therapy. I have a hard enough time talking to an individual therapist, but talking in front of a group will definitely be tough.

But thanks again for the information! I think I will get the hang of how treatent works in another week or so.
