I have misophonia and depression. There are probably other issues but they are undiagnosed.

I might have info that can help though! When I first started going to therapy, my therapist didn’t know what misophonia was, but she didn’t dismiss me. It is a therapist’s job to hear people out, and I think most are pretty good at it. My therapist even brought up misophonia at some sort of therapist conference and asked for other therapists’ opinions and experiences. She did her best to help with the issue, and also listened and learned. That’s just my experience, but hopefully you will also have a similar positive experience talking to a professional about misophonia! Hopefully it is the norm.

Also I don’t know if this really answers your question at all, but I hope it was at least a tiny bit helpful? Lol
