For me, "Writer's Block" generally comes from a place of Self-Doubt. When I am going through something or am in a low phase emotionally, my writing gets crippled as well.
I usually write about my life, past journeys, stuff I've navigated through and learned from. Now, writing about a past accomplishment or even a realization seems fraudulent because if I was genuinely successful at it, then why am I here again, going through the same problems?
Over time I've found that pushing myself to write the planned piece during such a time doesn't end well, ever. Depending on my situation, I do anything from taking a break to switching to an article that's easier for me to write.
I often resort to humor and poetry. I've also written about what I am going through at the moment, sort of unleashing my stream of consciousness on a Google Doc.
Sure, it reads a bit like a journal entry, but at least I've written something. Not writing for a while starts another whirlwind of doubt, which tells me that I am not cut out for this.
Thus, I choose to write, whatever that may be.
Removing the pressure that a particular article needs to be written at a certain time and choosing to take my mental health into consideration before setting short-term goals has solved the problem for me.
It helps me feel unblocked and slowly brings me back to the state of flow, where I can write again.
