Tips on talking to a GP?

Hi, in a very severe and long crash but my caretakers have helped me get a telehealth visit with a GP and I am wondering if anyone has any advice for getting treatments prescribed.

This GP works for a progressive practice but is probably not literate in MECFS.

I am hoping to start a sleep med, maybe an alpha blocker, and even klonopin as benzodiazepines help me when used sparingly.

I feel like these meds are a big ask as I don’t even have a CFS diagnosis—if you are on these kinds of meds, how were you able to get them prescribed? How should I talk to the doctor about my condition?
