I have BDD. It kind of goes along with all my other weirdness. My T doesn't really treat this either. The person on my team that challenges this the most is my dietician. She is full of super fun exposure therapies. The thing she does though is make me say out loud exactly what I see. She then tries to help me se the other side so to say. She has been very helpful in educating my T both of them actually. Even if you don't have diagnosed ED this may be helpful. My D is a specialist in intuitive eatting/ eating/feeding disorders. She was the first ED specialist I saw and even though my T has changed from IP to op she has stuck by me. Just an idea
