That's quite the terrible story.

And I honestly couldn't tell you why the second therapist claim it wasn't what it was, there may be variations in the exact legal definition between places but your description doesn't seem to leave any possible ambiguity in my eyes. That just sounds like a strange and pointless way to re-victimize someone.

Honestly, this is just beyond awful, you were abused by someone who was supposed to help you, then the next one seemingly gaslighted you for no apparent reason. I think it's admirable you had the desire to keep trying with mental health professionals after all that, I hope the current one is at least not an absolute piece of **** to break the trend.
