I get it. When I was sick after the holidays, I skipped writing for many days and I didn't know where to go after. It was the same for my video ideas, I didn't know what videos to make.
I guess that's why I'm always writing some sort of fiction too. When I'm not writing fiction, I'm writing Fan-Fiction. I'm always somehow writing something.
But it's also normal for our brains to get foggy after being sick or when we need a prolongued period of rest. Getting back into the beat of things is done best gradually for me, before I can be a peak efficiency again.
Hope you're feeling better though.
