Your stressing too much.
Write don't care about the word count. Don't care if it makes sense. Even if it's 50 words about the sociological impact of butterflies on humanity.
Forget about delete or backspace. They are the bane of the blocked.
If it not a necessary piece with a deadline step away from it. Approach the topic again with some different insights.
If it is a deadline piece screw writers block sit down and write. Then have someone else look at the piece. If it is readable comprehensible and understandable go with it.
Do no overedit yourself.
