I haven't been through this exact wringer, but reading your post makes me want to say, Just Slow Down & Breathe.
You already know so much of this is out of your control. You already hired great professionals you trust - legally & therapeutically. (and no, you can't move in with either of them...
)
You can focus on breathing through those moments of discomfort - it's the only thing that's going to change the way you feel. 3 deep, slow breaths is enough to reset the fight or flight response & keep you out of panic. You can't prepare for everything because you can't know exactly how everything will unfold. I know it's scary - the uncertainty is far worse than anything, IMO.
But breathing & short 10-min meditations help me stop from going over the edge in my day-to-day.
I also picked up these in the cranberry flavor for short-term use because I didn't want to start taking an anti depressant for a short-term, situational discomfort... they seem to help quite a bit:
