I just realized that it may seem like I stalk you, since I almost only write in replies to you Its just that I read everything in here, but for some reason have this strong urge to try and help you! HOpe you don't mind

Can you maybe ask her if she believes you when you talk about things the mother did? More as a general question, instead of specifically the radiator thing. Would you ever consider recording a session? One where you were really scared, or was afraid you were getting triggered? Then you can go back later, when you are calmer and listen to T's response and see if it seems different? It might help.
