I'm sorry you are dealing with all of these anxieties.

You have the swelling in your leg to be concerned about plus it's the anniversary of your mom's final days & passing, & other problems such as your generator not working. So you have a lot of troubling things coming together all at once. It's understandable you would be feeling a lot of anxiety.
In my case I think this whole coronavirus pandemic situation is just making everything seem even worse than it would normally be. I'm personally not even that anxious about the pandemic itself. I rarely leave home. So about the only way I would contract it would be if my wife got it. And she doesn't go out all that much either. But I notice everything just feels darker & scarier to me whether it's related to the coronavirus or not.
For a while now I've been experiencing something that seems to be akin to what is referred to as "Sundown Syndrome". And I don't know if it's because of the pandemic situation or not, but my sundown symptoms seem as though they're becoming more intense lately. Recently I had to learn how to use "Zoom" in order to have a virtual doctor's appointment. And the anxiety I developed over that process left me shaking.
Anyway... I didn't really have much of anything in the way of useful insights or suggestions to offer you. But I thought I would just let you know I read your post & share a few of my own current anxiety experiences. Hope you are able to begin feeling more calm & at ease soon.
