Ah, that's unfortunate. Perhaps you can find a writing partner somewhere to do sprints with.

There's been plenty of other good advice around as well about writing first and editing later, but if you are someone with dice around, a prominent, prolific, and published author once shared that if you have a die, you can use it as a word tracker. Every hundred words, turn the die so that the next number is up. Then you can see progress. (And double sixes is 3600 words, even if it didn't feel like it.) Or you can use some of the tools like Written? Kitten! to give you adorable imagery while you put down words.
