I'd steer clear of benzos.

A med I found that helps massively with anxiety is gabapentin. I was prescribed it for shingles, but it evened out my mood and made me feel so laid back that I decided to look it up. Turns out it's often prescribed for anxiety. I'm actually going to ask my pdoc for a prescription.

It's non-addictive and apparently can be taken PRN. I take 300mg and my anxiety goes away. Even my social anxiety is better.
