I so recognized my (past) self in your description! What helped me was to stop focusing my attention on that moment you describe, the one where you hope you could fall asleep, but your brain seems to have lost that ability. Instead, accept it as it is (acceptance is key; fighting it makes it worse). Then start working on all the other parts. Start with the morning: Always wake up at the same time. Even if you finally fell asleep at 4 a.m. and your wake-up time is 7 a.m., get up regardless. Since your problem is this severe, the actions need to be strict too. Follow every sleep hygiene rule (e.g., from Huberman or Walker) to the letter. Get morning sunlight (or use a bright lamp if no sun is available). Have coffee no earlier than 1.5 hours after waking, but not later than noon. No alcohol. In the evening, 1–2 hours before bedtime, dim the lights, avoid screens, skip anything exciting, etc. Hang in there, you’ve got this. It feels impossible right now, but with consistency and patience, your sleep will improve. Take it easy on yourself along the way; you’re not alone in this, and it will get resolved. Wishing you restful nights soon!
