Anxiety medication?

So I am thinking about making an appointment to talk to my doctor about anxiety medication. I have always struggled with it but always avoided situations where it was bad. For example I have really bad social anxiety so I always worked in the back of my office space or only with a few people who I already knew. I’m in college now and i also work at a hospital, I’m around a lot of people and it’s always super hard for me. I have trouble putting together sentences, my hands shake, it’s not even that I’m “nervous” it’s just like a bodily function I can’t control.

I’m nervous about being on anxiety medications (hahahaha the irony). What kind of things should I tell the doctor? What kind of questions should I ask? What if I’m drug tested at work? Does anyone else who’s on it have any advice ?
