Granite, i think its that simple. She is wrong, doesn't understand about radiators, etc. it is NOT her not believing you, i firmly believe that.

Look at you, figuring yourself out!!! It is good for you to look at it, in tiny glimpses I think. Of course you are going to get severly triggered when this stuff comes up because it is absolute awful what your mother did to you. You shut down very easily and quickly (and understandably!!), and don't give your T much time to capitulate on everything you are saying. I think you shrink down to survivor mode and can only think either "she hates me" or "she doesn't believe me," when in fact she has said things to you that very clearly indicates that she knows awful things went on.

is this therapist a trauma therapist?
