I had a similar experience. A shrink met with me once and told me I would be 'too much' for his therapy group. Actual words.

The context was, the one hour a week therapy I was receiving at the medical centre was not enough. I became suddenly desperate, and told my regular therapist that.

I didnt expect them to come up with a magic solution but I was young at the time, and had no idea what to do with this feeling.

He made this comment and sent me home. It really hurt my feelings.
