I'm in the U.S. The abuser in my case was a psychiatrist. Psychiatrists are medical doctors with special training.
There are many ways to seek justice and stop an abuser. But it's not easy.
This is what I did:

-Reported him to the police. Criminal charges were considered.
-Reported him to his medical board.
-Filed a civil suit
-Reported him to my insurance company, Medicare and Medi-cal

If i experienced malpractice again of some kind at this point in my life, I doubt I would report again. The legal system was another major trauma. I don't think I could do it again.
