@cupfish, you mention yoga; have you tried adding in some exercise that elevates your heart rate for around a half hour per day or more, if you're physically able to do that? One can't start too fast. There are lots of options depending upon joint issues etc.
I try to get the rate up past about 120; this depends upon age. (How did I get to be this old, by the way????) For me, this seems to help burn off the results of random fear during each day, and sort of resets my nervous system to a calmer state. It's a maintenance thing for me, not a cure. I think adrenaline is partly to get the body to perform better in physical emergencies, so it's always made sense to me that working some of it out physically into some other chemicals would help my whole system. I feel calmer after, more so than sitting and trying to calm down, if I've had a lot of adrenaline. In other words... For me, there is often a level that is hyperaroused but the calm, deal-with-reality-and-look-normal part has always been there too, sort of a two level awareness; what I assume is getting rid of some adrenaline chemically through exercise makes me much happier than just medicines did.
