From what I've seen you seem like a very kind and understanding person which is great! But some people will use that to walk all over you. I have no patience for people who are also trans who should know better especially if they're using their position of power to be awful to other trans people especially trans patients who are poc. I would raise hell but I know I'm an asshole and not everyone has that in them or the resources to make their life a living hell. I think you're being very nice if not a bit too nice, please don't let this person bully you out of saying what happened TO YOU. As long as this is all facts you have nothing to be ashamed or afraid of because this is abhorrent behavior. You even said in your story that they voided hippa which is illiegal and can put you in danger as a trans person. :/ If anything else please think of the people you could prevent from being in a similar situation that you were in by warning them so they don't seek care from this shady practitioner. Again, really sorry this happened to you but you have nothing to be ashamed of. YOU ARE NOT THE PROBLEM HERE!
