That's pretty much what's happening yeah.
I had a letter from Doctor Curtis which I gave to her explaining my circumstances and that I would be prescribed T after blood tests were done. I explained to her what I would like to happen after the blood tests were complete and I had the green light to start T, she accepted what I had to say, asked to keep a copy of the letter and said that when everything was done with the tests and I'm ready for the next step we would sort out the prescription.
My girlfriend is concerned that she may no long want to write me the prescription if she's leaving the practice, in which case I will need to find someone else who will, and hopefully they will be as accepting as the old doctor. If she can start me on it that would be great, and like you said I can just find someone to continue it, I'm just worried there's going to be a problem starting it and I'll have to wait ages.
