I have been with her now 4x. I have talked about my upbringing and that that is the motivation why I came to see her. Then the breakup happened, so the last two times we talked about that.
Apparently she is specialised for adult children of complicated parents. And apparently next time we will do some questionnaire or something. So far we have only talked and she suggested one book ("iRest - Healing PTSD") which I started reading. She is supportive, but so far she mostly said I should find things I like doing, join sports clubs, try mindfulness and basic stuff like that. I know that my issues run deeper.
