Hey Tessa - glad to see you back on Medium! :)
In my experience, writer's block is something else manifesting as a reluctance to write. Sometimes (especially in 2020), it's general depression. Sometimes it's doubt about the piece I'm working on, or anxiety over how it will be received, or the impossible desire for it to be perfect. I've been writing for something like 16 years and I still get bit by it. The only cure I know of is to make myself think about why I don't want to write. And then to force myself anyway.
But give yourself some charity too. Sometimes you just need to step away for a while. Absence makes the heart grow fonder, after all.
