For the last year or so (if I'm honest, nearly two years now) writing has been far more difficult than it should be. By writing, I mean anything that requires putting words in a cunning order. Be that blog posts, letters, novels, or really anything. I managed to complete NaNoWriMo 2017, but it was torture and well, quite poorly written. For NaNoWriMo 2018 I never got past 14k words.
I have always considered myself a writer, not because I had published anything or because I was always writing something, but because I loved writing. Whenever the opportunity presented itself I would write happily away into the night. whether it was instructions on some process or system for work, a letter to someone, a short story, a blog post, or anything the words just poured out (not always good, but easily). This is no longer the case.
