I was reading another thread and thought, wow, has anyone here not been harmed by a therapist, and what is the reason? From what I've read, I can think of a few who have never been harmed offhand, but there seems to be so many, so I thought I'd ask directly.

It's choose all. I realize negligence can come from a therapist's personal issues, incompetence, etc., but these categories seem to match with the results I'm looking for.
