I get the rage Bert. Different story here, but same feelings about the perp and abusive parent(s). AND student therapists who have neither the experience or knowledge to do anything but toss a few book titles at you. Been there.
Nor - not what you want to hear prolly - do I have an answer, except that there's tons of empathy here, something like 11,000 of us on MS who have walked this path.
For now, just keep posting to get it out of your system. Sounds kinda useless, you and a keyboard, but I've found it actually helps a little.
