Not sure if I have body dysmorphia

Because the one time I tried to talk about it with a therapist, she immediately looked at that area and wanted to discuss it and knew she was going to ask to look at it and I straight up panicked.

It's a very specific part of my body that I can hide easily but it's also a part that pretty much everyone else shows no problem.

It's absolutely disruptive and distracting...

So. I guess I'm wondering if anyone has like.. Books to read or... Videos to watch or anything? About the subject or the psychology about it?

I'm not necessarily struggling with it because... I've been dealing with it for over twenty years... But I'd like to... Not. Ha ha.
