Thanks Glennk, yes I do believe there is a system in place to ask to meet a different GP if I wasn't happy.

Tbh, I feel I don't have the energy to stay persistent and to prove to the doctors I really need help. One part of me thinks I can fight this on my own, like I have before. Then there is other part of me which is really fed up with this cycle and wants to put an end to it all with professional help.

My supportive wife thinks we should see a private psychiatrist even if it is going to cost us for a few sessions to get a feel for what they think.

I am not entirely sure though which direction to take.
