Welcome Plenny
It sounds like you have been through a lot. Sleep is such a good thing. Get as much sleep as you can. I don't use the android app, but I use the iPhone app I know one thing that is really helpful is that I click in the right corner and click on subscribed and that helps me reply to the threads that I commonly use like this one.
I'm so glad to see you are back.
Stay safe and keep posting when you can.
Gentle
