Depends on if you've tried any meds already, and which ones.
We aren't psychics. But I will say that I was only 19 when my psychiatrist prescribed me Xanax at my first appointment with him. Actually, Xanax IR and Xanax XR. So it's not out of the question, but I've learned some docs don't particularly like handing out benzos to very young adults. Just due to the dependence liability and they don't believe for whatever reason that you can be trusted.
The first time my old psych prescribed me a benzo it was klonopin 1mg twice a day and before he even printed out the script he said "Ok so let's lay down some ground rules. No taking extras, no crushing, snorting, etc, no drinking, and last but not least, PLEASE don't sell them on the bench/steps in front of your dorm building (I was in my first semester of college and was 18 at the time)" lol.
Additionally, there are a lot of drugs to treat anxiety. Propranolol, Buspirone, some use gabapentin or pregabalin, Nardil (a rare one with tons of restrictions), and hydroxyzine to name a few off the top of my head.
Also, my psych actually prescribed me adderall XR off-label for "treatment-resistant depression" and honestly, it worked great for my anxiety too. Specifically, i was on addy XR for 2 weeks then switched to Vyvanse for about 3-4 weeks. It worked great, but my appetite was shit. I felt so sick if I ate, and if I'd eat, I would feel so sick afterward. So I got off of it.
Good luck with your appointment!
