I think therapy ends when the client feels he/she no longer wants it.

I intend to be in therapy for a loooong time .

There ain't nothing like plopping down on the couch/chair and have someone's undivided attention, and not have to give anything in return (other than $ of course...)

Therapy is a form of self-nurturing for me. Aerobics feeds me, hot soup feeds me, a massage feeds me, therapy feeds me......
