These types of questions aren't allowed. If you have a real anxiety problem, then you'd know what to say. A decent psychiatrist wouldn't start you off with Xanax right away, either. I suffer from generalized anxiety disorder as well as agoraphobia, I went through numerous anxiety medications until I got on Xanax, and I wasn't even trying to go that far. The withdrawals you would experience are horrible from benzos. A good doctor would start you off with something simple, such as Buspirone, and keep going along the line until you found one that works. Even if you DID get Xanax, it would not be a long-term thing most likely. I was on it for three/four months before I was switched back to Klonopin, and I'm not even on that anymore.
Don't lie to your doctor in order to get meds that you're going to use recreationally, when there are people with real problems out there. I'm going to assume you're trying to get it for recreational purposes anyways, since you're asking us how to convince your doc to prescribe you it. It's honestly not even worth it.
This thread is gonna be shut down.
