Writing can be joyous, momentous, creatively satisfying when it's going well ... but when it isn't, finding words can be impossible and the blank computer screen can be a vision from hell and the stuff of nightmares.
There is of course the old 'writer's block' where you just can't get to first base with anything; it's like a creative constipation. Nothing is moving and you need some kind of 'laxative for creative people' - hey, there's an idea! I can see that on the retail shelves already.
Then there are the times when I'm doing OK with my creative work but then 'life gets in the way' and something major happens. Maybe old Miss Betsy-cat gets worryingly sick, the plumbing goes bung or I'm unwell, then I develop a one-track focus. I give all of my attention to the problem and I cannot do any writing. I've always been like that. I don't multi-task too well.
When this happens, I have to take time out. I take my lead from Betsy. She just lies down in the sun.
With a 'writer's block situation' I have some tools I use to get started again but when there's a life issue, I have learned to ease up on the laxatives and just stop.
It took me a long time to convince myself that this was OK because I always believed I should be able to write, no matter what else was going on in my life. That is still mostly true because if we let life overtake us we would never write a word. But when there is a life event that requires my focus to really be there, right with it, then I stop and that is OK.
When the going gets tough, the tough sack out.
It's OK to to take time out. If you can't write because your emotions and concern are elsewhere, do whatever you need to do to take it easy ... and give yourself permission.
I am jolly lucky because I can sit out on the deck and look at the sea or the trees and the birds and I feel surrounded by friends and comfort. And always remember that tomorrow is another day.
You can try again.
