I have terrible panic attacks and anxiety. I've tried almost everything. Hydroxyzine, valerian, counseling, three antidepressants, deep breathing, mental exercises, and Xanax. Xanax is the only effective thing that worked.

Some were beneficial, some were not so much.

I have GERD, IBS, a stomach ulcer, and scoliosis.
Are there any supplements for anxiety that don't interfere with said conditions?
