Group Therapy

My DR referred me to a CBT (cognetive behavorial theray) group.  I've never been to one before and the book this group uses is "Ten day to self esteem" by, I think, David Burn.  I don't believe that I have a self esteem problem and am thinking of not joining the group.  I've been to other self-help and 12 step groups before.  It's also a late afternoon meeting, 4:00pm to 5:30pm, which would mean I'd have to take a half day off of work without pay to attend.  I may check to see if and when another groupd meets at a time that is more convenient to my schedule.  Have any of you folks been to group sessions and what are your feelings about those?  Thx, Thom.

I found it really hard to open up in a group session.I have done much better with a therapist.maybe see about getting a therapist would make you feel more comfortable. good luck
