My mom embarrassed me!!!

My mom came to my pre op appointment for FFS to learn how to take care of me after surgery and find out what I’m getting done! I asked her to literally use any pronouns other than he/him and of course that’s all she ends up using the whole appointment. I felt so embarrassed and disrespected. It was suppose to be such an exciting day for me and it got completely ruined. I’m just really upset that no matter how many times I correct my parents and ask them to use the right pronouns they just don’t and refuse to try.
