When biting words are tossed at you, I feel, part of the hurt, because it can feel shameful, to have a diagnosis of any kind. At the same time, you aren't the only person on this planet, to have what you have. Remind yourself, in the moment, maybe the part about having a mental illness in your medical chart, is correct, at the same time...think to yourself, at least, or even say outloud. "Don't talk to me, like that. You have no right to talk to me like that."
Guess I am trying to say, don't buy into the shaming aspect of being told to take a pill or whatever she says. Don't be ashamed for what you have, is a start. It just is.

Demand respect, don't let anyone 'hold' this over your head. You aren't so different than the rest of the universe.
