You CAN use a primary care doctor to get your insulin prescription when you can't make it to see an endocronologist. You need to pick a primary care doctor and try to get an appointment for a full physical with a primary care doctor. That primary care doctor can prescribe you a three month supply of your medications and then they can also recommend an endocronologist for you to continue care with.
It is usually much easier to get in to see a primary care doctor than a specialist, so you shouldn't have too much trouble getting an appointment. Then you will have a regular doctor to go to for you non-diabetic needs also.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
