I'm with CE. The "lost 12 months of progress" statment would have hurt me very very badly.

I would also likely feel very shamed and very chastised over her response to the email.

Sometimes it helps to try and see things from all points of view. Sometimes it helps to recognize what belongs in the past and what is now.

Sometimes, however, things just hurt. I see a lot in that session that would have hurt me.

I agree with you. There is something wrong with the way your therapist is interacting with you. I would likely feel as though I were being gaslighted as well.

I'm very sorry this is happening. I have absolutely no idea how I would handle it.

I wish you peace with it however, and wisdom as to what to think.

Is there anyway you can just let it "be" out there for awhile. Maybe it will look different in a couple of days?
