I have an extremely difficult time falling asleep and staying asleep. I have never understood how some people can pass out as soon as their head hits the pillow.
My "sleep debt" is ridiculous. I don't think I will ever be able to catch up, and much of the damage from missing so many hours a night is already done.
I think there are several contributing factors, such as having a very active mind, even at rest, and having an extremely stressful and anxiety ridden situation enveloping me, which can lead my febrile mind into a frenzy, having only traumatic substance to sustain itself on.
I also have pretty severe jaw pain that has gotten progressively worse, and because of a poorly structured jaw/face as well as complications from poorly done procedures, I have an awfully hard time breathing and getting enough oxygen to my brain. When I lie down, all these issues intensify, and even if I do manage to fall asleep, even if I somehow got a much needed 8-10 hours, it won't feel like that once I get wake up. I never have that refreshed or well rested feeling, likely due to not being able to breathe properly (and writhing in discomfort).
All my dreams seem to be nightmarish in nature, as well, I can't remember the last pleasant dream I had. Still, they are all preferable to reality.
