I can understand that a T might be worried that one would do too much "processing" here - and then avoid bringing issues into therapy, or that one might get bad advice here (though I think the advice here is usually spot on, given how many people response, bad responses get overruled pretty quickly!)
I also think Ts may not realize how *supportive of therapy* this place is. I could not have brought in some of the stuff for my T that I have if it weren't for this place... because everyone pushes folks here to bring big issues (or issues with the T-relationship) to their T!
Anyway, I've mentioned it a couple times to my T, but didn't want to get into details or tell him the site itself - I don't want to risk him reading my stuff!
