I don't think you are wrong to feel how you are feeling. You have that right. My concern is how you respond to them, i.e. dump your therapist.

I spent a lot of my life either staying silent and not dealing with the similar feelings so they ravaged my body or I responded way out of proportion to life's events and would cut of my nose to spite my face. It was a lonely place to be. Living that way did not allow me to move forward in my life. Your therapist taking the blame is major to me. Many people on this forum complain about the 'I'm sorries' their therapist provide as not being enough, so to hear a therapist is actually willing to take the blame is the biggest I'm sorry one could get. That's my thinking about your post but I am totally a different bird on this forum when I respond.

I hope you can find peace soon.
