Funny story:

I went to a support group with my wife which was held in a business building.

We went to the wrong room and were a little late. Everyone got quiet when we entered. The apparent leader of the group asked us why we were there and welcomed us.

After a couple of minutes of explaining my situation, I was getting blank stares.

It turns out it was an elderly massage class. The real room was one down.

I'll never forget that. After that whenever I have been to group therapy, I have had no fear of sharing.
