I had years and years of therapy and the last therapist DID terminate/reject me, leading to the experience of the feelings and, eventually, memory of past similar feelings that comrademoomoo expressed so well. I was not aware of the fears or the past feelings -- I had very good defenses, I guess you could say, despite my best conscious efforts to get to the bottom of things. And never found a therapist who could tolerate my feelings and help me get past them.
Hopefully this therapist CAN help you -- but the void can lead to very treacherous waters, too. So, just so you know. And to validate your fears.
I had acted toward my daughter sometimes like my mother had to me, too. It scared me and I took her to therapy and went myself, too, as I said. My daughter is now grown and with a family of her own. We are not close, but she does seem to be doing OK. Her kids, too. Hopefully.
