Sorry to hear you have been struggling for so long with little relief. Here are some ideas off the top of my head as someone who has also struggled with anxiety:

1) therapy such as CBT
2) neuromodulation device such as Alpha-Stim; I’ve heard these are very popular at the VA so maybe it would be easy to get covered by insurance for you
3) natural supplement Silexan, which is pharmaceutical grade lavender oil that you take as a capsule - shown to be just as effective for anxiety as prescription Rx, with no side effects to speak of. Some evidence for efficacy in MDD as well.
4) yoga, meditation, progressive muscle relaxation, diaphragmatic breathing - any of those sound doable?

Keep us posted and hope you feel better soon.
