I agree with BonnieJean, sounds like your t was having an off day and her frustrations came out a few times in session. She was not in tune with your needs and didn't validate your emotions- these are very painful experiences as you well know Rainbow.
Sounds like there was an agenda for your session, was it hers or yours, I don't know! Can you tell her when you are both going a different way in session and maybe say you want to spend a little longer on such and such and less on others. Maybe you and t gave different viewpoints about death and your t was trying to get you to look it differently instead of accepting and acknowledging where you are at in your own journey of life. I wonder could you tell your t when you start to get frustrated in sessions because you are left with a lot of frustration and difficult emotions at the end of session. You and your t gave such a good relationship, she would appreciate you talking to her about all of this. Maybe if you requested time at the end of session to ground yourself and to talk about these difficult emotions before you leave, could that be helpful
