If you are that agorophobic, you definitely need a good antianxiety med. Xanax and Klonopin are good. If you go off the Xanax after using for a period of time cold turkey then you could have seizures. That is why it is recommended that you taper off them. I have known people that have been using Xanax for a long time with no problems as long as it is not abused.

I also have panic attacks when out in public for some reason. This is a condition I have experienced just for a few years.
