As others have said, welcome!
I’m 61 and also from the UK. As another Brit, I can assure you there is no need to feel isolated! I’m in the Midlands, by the way, close to Oxford, so not so very far from you…
Of course, though, there is stigma and there are people who won’t accept people like us. But that’s their problem.
I’m happy to chat and share where we both are in our transgender journeys, as and when you would like.
