How do you come up with stuff to write about?

quick question to all the lovely writers out here

I used to loooove writing a lot, but lately my brain has been deepfried and I cannot for the life of me come up with things to write about. I really miss the times where I was typing away thousands of words after school hours to just get the ideas in my head on paper.

Somehow all of these ideas are now gone!

How do you come up with things to write about when it doesn't come naturally?
