Sucks to hear that you're having a rough go of it. Hope things get better.

I know you're quarantining, but are you still getting out for walks, etc? Obviously it's good to avoid unnecessary travel, but I think it's pretty crucial for most people to get a change of scenery, to see the world doing the things the world does, etc. I know it doesn't solve the issue that's bugging you, but simply taking your morning tea/coffee/smoothie outside and enjoying it while taking a walk around the block can help brighten your day.
