I just joined in - severe revenge/bedtime procrastination!

Hey,

I suffer from insane revenge/bedtime procrastination! I have chronic pain and depression last 6 years and you can bear TV shows/games only so long (they bore me more than watching a wall at this point actually - not kidding)... I have severe long lasting headaches: I can't even read anymore! I can barely read even sentence many times and rarely I can read like 15 minutes, but it sucks... 

I can't absolutely do anything whole day, even if I wanted!!! I can walk maybe 0.5-1km and already after 3 days: I have to take a break, because pain and it wouldn't be healthy - I have damaged spine... So 99% of my day time I have absolutely nothing to do... I can never rest and I Am never entertained (as bedtime procrastination is also if you don't have time for yourself)... 

I also feel urgency to do something with my health and it is complicated, but I fail all the time, because I have also severe executive dysfunctions and ADHD (likely dopaminergic issues and brain inflammation)... I can't get anything done, I don't know how. At this point I Am like robot, I have 0 self control and whole day I Am feel tired and drowsy: I have also cfs... 

I can't sleep on 99.99999% because boredom (I suffer from hyperbolic dyscounting)... It is because of pain being bored to the oblivion, but not having any other options! I always defer going to bed even 500 times from 11Pm to 3-8AM!!! I need to watch another video, read another article, listen to another song... Even thought of going to sleep causes huge pain in my brain and on my chest... Which also creates stress and is not good!

I read over thousand articles about this, but nothing is really helpful. Because I can't do anything with my boredom likely years, or months in best case scenario which I doubt! As I will be bored until I can read again... Nothing in upcoming months and years will entertain me more than watching a wall and that is just fact! How one endures such a torture? People rather chosen electro shocks than to be 15 minutes with their thoughs in a room and boredom is used as a torture, as it is pretty awful!!! I need techniques to resist torture of boredom at this point!!!

Even if I did everything perfectly from now on again it will take months min. likely more, before I will be able to do anything which doesn't bore me more than watching a wall (in a most literal sense). How would you endure watching a wall months to years all days long??? 

I need to force myself to go sleep on time, but I have no idea how to do that!!!

PS: even if i force myself to do something over 10 minutes, it hurts pretty much every second... Also even if go sooner I may end up not sleeping 3 hours in 5-6 am and fall asleep later actually...
