Severe revenge bedtime procrastination + chronic pain

I suffer from chronic pain last 6 years and I can't do literally anything more stimulating to me than watching a wall whole day. I used to read Philosophy 16 hours 24/7, but my state worsened and I can't do even that anymore! Nothing I can do is more stimulating/interesting/entertaining me more than watching a wall! I Am so bored (especially before sleep) I keep bedtime procrastinating from boredom last 6 years. I defer going to bed even 500 times from 11PM to 3-8AM while trying every second! It is literal torture, I experienced even 9/10 maybe 10/10 pain and it is nothing compared to boredooooooooom!!!!!!! What is worse I face also existential boredom and I have need for cognition, not being able to do anything whole day for me is worst punishment than torture!

I tried to read thousands of articles, but I have hard to implementing solutions, or it is N/A to me, or it is long-term problem (but I suffer from CFS) and procrastination, I can barely do 5 small tasks of work like 15-30 minutes a day...I have severe executive dysfunctions, even smallest tasks like cleaning my teeth overwhelm me. And I Am in pain constantly whole day, I can't remember anything, or think clearly. I have so many problems: it is inhumane! And I have no friends and I live with toxic mother, which won't help me with anything. So I Am completely alone for everything...

I don't know how to force myself to sleep, it is so important, I need to go sleep early literally everything next in my life to get better!!!! Every night I get 2-3 hours before bedtime insane anxiety like pain at heart and knives in stomach! It hurts in whole body like being whipped to the bone! And I always procrastinate at least 1 hour. Currently I go like at 12-1AM. But I have to get to 11PM stable sleep schedule every day!!! I now turned my sleep from 6-8AM to like 12-1AM, but still I wasn't able to sleep one day like 3+ hours, I can't sleep many times 2 min 3+ hours because I have also deviated nasal septum, so I can't focus on breathing it is insanely uncomfortable my nose feels after 7 minutes like a rock and I feel scaffolding inside. It is humanly impossible to sleep like that. So I always think in bad, but it is worst thing you can do. I have also ADHD and I never in my life fall asleep like this. SO I also suffer from bad insomnia! Melatonine and these things don't work and usually have side effects... I take sleeping pills just one small tablet, but it is still torture every day to endure this!

Worst thing is: when It is time I get so anxious and bored mostly before sleep and when I have to go: I always fail to make myself to go. It is so painful even to think about going to sleep! And I hate night hygiene it is boring! But I can't continue like this, I will die from pain, it is inhumane torture no joke! I can't every day 3 hours be doing battles to go sleep and it is painful like torture every second. I read thousands articles, but I AM in pain I can't solve this alone any time soon. I will also try contact pain doctor, psychologist and sleepo doctor maybe, but... I need every advantage I can get right now! Worst thing is this boredom whole day. I can try to do anything not forcing myself, I set timer like for 10 minutes and say to myself: lets try this I can stop anytime. But anything which is not science and philosophy feels like someone is breaking my fingers with hammer - not even joking! I need to work 16 hours+ 24/7 and every second I Am not doing something productive is torture to me worse than choking to death and worse things...

I don't know how to force myself when is time to sleep. Even if it would be painful, at least I would go and then is next day. Problem is I Am not strong enough to force myself. I also suffer from anhedonia and delayed pleasure, my brain is programmed for far future. I Am not looking forwarding for anything next 10 years... It is so tough I suffer from so many things, it is insane! What I have to do every second to even stay alive and smallest things are pure torture and hell! I don't know what to do, I Am so dejected and desperate... I have so many problems every day and so low energy, i don't know what first and executive dysfunctions, I Am procrastination on relatively simple things years, it is worst it can be literally. I need help before I can help myself, but no one wants to help me... People are useless...

I can try to relax before sleep doesn't do much difference... Even when I AM not anxious I bedtime procrastinate from pure boredom, because my brain can't tolerate boredom and there is nothing I can do, I can't even read... I have hyperbolic-discounting... Problem is i even know cause and solution, it is from boredom on 99% but i can't do anything with my boredom next 2-4 years, before I get better so i can read, so it is catch 22. I have all symptoms of prisoners in isolation!

I don't know how to do anything, how could I force myself to go to sleep when it is time????
