You're making sense. Van Gogh is a bit overrated, but Lewis Caroll is great. Anyway that wasn't really what made much sense.

But the hypersensitivity does.

I'd suggest you go to bed at say, 3 or 4 am. The chances you are tired are higher and you don't get hypersensitivity which really doesn't help with sleeping.

There are ways to make insomnia more bearable. Not resting when you're not at all tired is one. Resting will make you mad and you won't sleep much and possibly feel more tired when you get up. But it's also about not caring too much. If you just relax and just lie there, the hypersensitivity will be less severe.

I didn't sleep tonight but I possibly feel a lot better because I don't have hypersensitivity that stays with me when getting up and I might also be less tired. Definitely mentally less tired.

Or just rest for 30 minutes and then do something else. But only if you otherwise won't sleep for a few days. So likely only when very manic or depressed. Try not sleeping for one night. It won't kill you.

Hope this will help.
