Are you able to send your doctor an email or a message? Sometimes it's easier to start a dialogue that way.

I love making lists, so I don’t forget what I need to talk about during my appointment. I messaged my doctor the same list so she has a copy of it beforehand.

Write it down. That's what I do. I'm a really good writer but really bad at talking to people. You can either just have it in front of you and read off of it or you can hand it to whomever you want to read it. Or you can email about it or mention it specifically when you make an appointment depending on how your doctor's office is set up.
