This should be pretty widely available. I got mine done through my GP, although it was recommended by my pdoc, and that was a few years back now. If it’s available here, it should be available most places in the US.Some places will offer to genetically test for the best possible meds after a few years if needed.
Wish it had been available sooner - it identifies which psych meds are likely to give you significant side effects. It would have saved me more than a dozen different med trials if I’d had it sooner.
Hope things are improving for you @PlainJane . Ease back into life as slow as you need to.
