Do you suffer from inability to concentrate? I find that when I shake, I can't concentrate on anything. Exercise doesn't do much for me in those situations. But just doing some chore or other will help calm me down. I think it's the fact of accomplishing something that helps. Otherwise I sit there like a quivering piece of jello unable to do anything but shake. Xanax helps, though lately I've needed something stronger like klonopin. The meds don't take away all the anxiety but they do lower the stress level to something that I can manage on my own.

The shaking sounds pretty bad. Meds can help bring the level down to something you can handle. Over time you can gain more ability to handle what brings on the shakes and thereby use less of the meds. Yes, benzodiazepams can be addictive, but they aren't always.
