Isn't that exactly what Perls did in his session with Gloria?
It sounds like a very damaging form of Gestalt therapy your first T is practising. Incredibly outdated and irresponsible to say the least.
I know it's hard (especially with a T you have a history with) but try not to blame yourself for this. You did what you felt you needed, and she clearly has no idea about what you needed from her. I think this experience might be a valuable (albeit painful) reminder that she can't be of use to you going forward. I hope you can draw on the support of this board and better therapy in order to grieve that loss.
