((((SAWE)))))) You do such amazing work internally !!!!! WOW !!!!
That is amazing how you could see through your feelings about T returning and feel about your mom.

I have an idea just to toss out there. When you see your T next, can you say "I need to correct something from my mom." Tell her just to stand there and you will walk out and walk back in and say "Hi Mom!! It is good to see you!!!" Have your T say "It is great to see you too!!! I actually got in a day early but I know you didn't know that. I am sorry I didn't call you to let you know. But it sure is good to see you now!"

For some reason I sense if you did this little role-playing with your T and then go over it, I bet the proper response in transference would help you heal from that very negative real response you got from your mom.

Tons of hugs!
