I would suggest that you have a plan B in place.
That is always a good idea!
Many years ago, I remember reading an article in the NYT about how to survive a a major incident: cinema fire, tube disaster, air plane runway crash, earthquake .... or whatever. Apparently, statistical, you are much more likely to survive if you
always prepare a 'plan B' for what to do when things go sideways.
On the subject of Doctors:The Doctor patient relationship is one of trust. So, if you have no confidence in your current Doctor, then you really have to change surgeries. In my view, if you cannot trust your Doctor, then how are you going to be able to open up and tell her/him those deeply personal things that he/she really needs to know to accurately diagnose whatever ailments you may have.
Incidentally, trained professionals, like Doctors, are highly observant and, with even a cursory examination, can tell a lot about a patient's private life from little clues in their fingernails, hair, eyes, general appearance and demeanour.
