I was prescribed a benzo for insomnia and it helped for that, so I kept taking it. Eventually I developed severe tolerance and started having interdose withdrawal. Between the interdose withdrawal and rapid taper my CNS and stress response have taken a hit.

I have not had any serious anxiety issues in my life until withdrawal from benzos. I have, developed a predisposition to worry, to have disproportionate responses to stress due to the neurological, physiological, and psychological trauma caused by withdrawal from it.

I have found Ashwagandha extract and L-theanine quite helpful. It's interesting noticing how they affect me. Stress is still stressful, but it is not overwhelming. However, I learned the hard way that benzos and ashwagandha don't mix well, or rather, are tricky to mix to the point that it can be dangerous. In some ways mixing them increased my rate of recovery and in others took a toll I paid dearly for.

Yet, now, it is entirely beneficial with the only unpleasant aspect being it's diuretic action. I'm still recovering from the damage done to my CNS, but it's becoming clear I'm reaching a point that I can reduce the ashwagandha and adjust the Theanine. For me it's wonderful stuff, but some people respond differently, though, not in the way people differ in psychotropics, nothing so serious.

It's best to work with a psychiatrist when integrating substances like these into treatment as otherwise it requires a great deal of research and experimentation with no one to help at least offer some educated perspective. Examine.com has useful summaries and lots of citations for many supplements that would be of use to a clinician in assessing potential interactions between medications.
