Cut down on caffeine. Possibly take a vacation. I've discovered is that when I'm on caffeine, my stress levels are extremely high (around 90%) and energy levels are equivalent to at 1 AM (as measured from a smart watch). This gives me an ADHD-like effect of being hyperfocused but unable to do important things. By comparison, on a normal day, under harsher conditions, I'd have much lower stress levels (30-55%) and a lot more energy. The brain interprets the physiological response based on context. It's a bit complex to explain in a comment, but look up the Schachter-Singer Theory. So you might have the fight/flight/freeze response, which results in procrastination. Some people condition themselves to fight (anger/insults/action). Some condition themselves to freeze (inactivity). Spend too long in this phase, and you condition yourself into inactivity. But the actual pressure from not completing the work makes you stressed and it becomes a loop.
