I know all too well what you are describing Purple Heart. It's a lot like being in one of those ongoing television series where a person is expected to play an ongoing role and is type casted and just recognized as that certain character. Marilyn Monroe for example wanted to play different roles in movies and yet continued to be expected to play the same kind of role that proved to be a money maker as a dumb blonde sex goddess. She was actually very intelligent and capable of doing more serious roles, yet kept getting handed the same type of character anyway. Well, that is how human beings tend to be where a person is so young that without realizing it that person slowly gets put into a role that may not be healthy for that person. That can happen within one's own family and there are times where it's just too toxic where the best thing to do is distance completely so the person has a chance to develop their own identity and not have to be stuck in a role where the person ends up being neglected, disrespected when they don't want to continue to play a role that makes them unhappy.
