I’m wondering if you are still reading OP.
I hope you can sidestep the responses that come from ignorance of what misophonia is. If I hadn’t experienced it myself, I might think like that too.
it must be so distressing for everyone involved, you, your daughter, and the rest of the family.
I’m wondering, does your daughter understand that it isn’t your fault, that the noises you make affect her so badly? Is this something you can talk to her about, when she is calm?
is she willing to try and control her reaction to her feelings? Can she separate those two things, the distressing angry feelings, and the acting out of those feelings?
it sounds like hypnotherapy might be worth trying. There’s a lot of different hypnotherapists out there, and some are not as highly trained or qualified as others. The best hypnotherapy qualification is someone who is also a psychotherapist and is registered with the UKCP. I worked with someone like this for an anxiety issue. I see he works a lot with different forms of OCD (misophonia seems to be related to OCD), and anger management, and is also qualified to work with children and adolescents. If you want his details, message me.
