Thank you for your comments
@Nick47. I say again that I visit this forum to try and help people and therefore, will put asside the impudence from the member that quoted my post to you, for it clear this person knows nothing about the way tinnitus and hyperacusis can affect a person's mental health, otherwise he would not have interfered.
It is your choice whatever you decide to do regarding private treatment. However, I don't think consultations with a therapist via Zoom is right for you. Face-to-face is better and preferably with someone that lives with tinnitus.
If I were in your situation, I would talk again with my GP, to see if it's possible to access treatment at a hospital further afield. I know you mentioned this is frowned upon but my understanding is, someone in the UK can get treatment at any NHS hospital that is willing to treat them, as mentioned on the NHS website. If my GP said this isn't possible, then I would politely say, that I intend to write to my MP for help.
I am not the type of person that gives up easily and therefore, will push and push until someone listens. Some years ago when I was living in London, I wrote to my MP about something not concerning tinnitus. To my surprise he raised my concerns to the Prime Minister, in the House of Commons, at Prime Minister's Questions.
