I hope you're feeling a little better now, Hopeful. Did you try anything to help with the stress? I've been walking a lot lately. And drinking Pellegrino as my treat. Deep breathing is a ready great way to biologically turn off your sympathetic nervous system, which is the fight or flight response command center. If you force yourself to slow down by breathing slowly, your parasympathetic nervous system (calm center) kicks in and starts to bring you back to a healthier place. There are apps with breathing guidance. I like Calm app.
I know your stress is probably something major and me suggesting breathing and walking might seem out of proportion with what your dealing with, but i hope something helps you find peace. This too shall pass.
