omg no one deserves that. It sounds like they were just some miserable people that wanted to make YOU miserable as well.
I was never diagnosed with any FPP but I know I have something like that. I use fantasy to escape reality and I've done that my entire life. I've always built castles in the sky. I used to make up stories when I was younger that were very exaggerated and i honestly even believed them at some point. I was never found out though but even if I was I would not have deserved to be attacked in such a way. I am so sorry that happened to you. I can't believe people are so cruel.
