You said that was a bit of a better session, but it doesn’t sound great -only maybe the end? I see you said and felt negative things about yourself ‘my sometimes immature behaviours’ and ‘irritable, argumentative, unyielding’. Maybe you are infact being mature, assertive, articulate and insightful? I can identify with you not wanting to use parts language. I remember saying to my T ‘the child in me feels...’ in an attempt not to be confrontational, but I regretted it, feeling that it had taken away from what I was saying.

I look back at the last few weeks with my former T and I wish she had been more accepting and able to take a third party stance and look at what was happening between us with some humility and respect for me. Maybe your T needs that too.
