When your brain chemicals are off, anti-anxiety drugs can really help you even it out properly.
Xanax is often prescribed as something youw ould take to stave off a oncoming panic attack.. OR as a maintanance dose to keep you from having the swings in chemicals that cause the panic attacks. I was put on the maintance dose of .5mg and it did quite well. You always want the lowest possible dose of drug that helps you.

If you think the xanax isn't going to work at .5mg then you may indeed make your stress levels rise just by worrying you'll have a anxiety attack. But give it a shot.. you can always have your doctor raise the amount later on, but I'd give it at least 2-4 weeks before you say it doesn't work.

Not all of the 'natural' remedies are safe either. You should always talk over all alternatives with a acreditted doctor.
