Looka

Anyone got advice for writing in a more linear and cohesive way when you've got brain fog and focus issues? I seem to either stare at screen for 5 minutes between sentences or skip around a lot, leading to an incoherent document with a lot of holes, both approaches that are extremely frustrating. Also, I've been getting weirdly impatient with my own typing speed? I'll get one sentence into a two-sentence idea and I'll want to throw my computer at the wall because my brain's already moved to the next thing.
