In the short time i've been here i've found it very helpful. Even just reading others stories had a positive affect. But the best therapy has been all the joking around that goes on here. If you jump in and join in you look back and find that the joking teaches you not to take your past in the jw too seriously.
I suggest everyone try jumping in a "live" thread where everyone is joking in real time. We did it a week ago and it was a blast! I think everything i've encountered here has been great.
