Hmmm, I can't help but think if I were you, knowing what your doctors have said, why continue self medicating?
Seems they've told you there are risks, but your defying their advice.
Personally, I would have transitioned regardless of HRT. While popping pills seems comforting, they are not magic pills. You'll benefit somewhat, but there are other things that can contribute more to passing ie. Hair removal, trachea shaves, other surgeries, voice training.
I know of a few trans who had liver problems, and HRT isn't possible. It did not stop them from going full time. In fact, one of them has been a stewardess for years.
