That's not me

[Twin Volition]

We had problems with names for a long time too, but eventually we got people to use the ones we preferred. I agree, it feels very degrading for people to dismiss who you are, even in small ways. Self-image and identity are already difficult and complex as it is, so the least people can do is not make it worse by using the wrong names.

Have you tried explaining to them why exactly it's painful to be called a certain way? From personal experience, I can say it's sometimes a simple matter of misunderstanding. I'm sure they don't mean any harm by using your full name or suggesting things about your appearance, so maybe if you got them to see what makes those things objectionable, they'd be willing to cooperate.
