You have posted in the correct forum.
I have BPII, so I don't deal with mania.
I do, at times, experience high anxiety and noise sensitivity. It can be quite bothersome.
I am sorry you are going through a difficult time. I an glad you are working with a therapist and hope doing so is helpful to you.
Seeing the doctor tomorrow? I'd suggest telling him the truth. he may be able to help?
I am sure others will be along to comment in a more helpful manner.
Please keep us updated on how you are doing?
Take care!
