I think, in that guide to therapy etiquette, thereally should be a part where you react to a therapist getting your life mixed up with someone else..... (happened to me)
Also pausing to figure out what lawyer she could send you to who wouldn't be "put off" by you....... ( also happened to me)
I stopped seeing both of them, but the first one, it was because she told me I wouldn't be able to reach my goals, not because she forgot something. That is just being human, but it still can make you feel bad.

I want to know if I am just difficult, or if I did the right thing quitting those two counselors, but I think even if I did them"wrong" thing, I just couldn't make myself go back after that. So maybe there is no "proper etiquette" in this case.....just what is right for you.
