Struggling with Sleep: Can't Stay Asleep

i don't know exactly how to explain this but. sleep is kinda annoying to me? like i keep waking up in the middle of the night or early morning and i just wanna stay awake. going back to sleep feels like too much work i realized that part of the problem is my pain, cause laying down doing nothing doesn't offer any distractions so i wind up being really uncomfortable. but other than that i'm not sure why i tend to avoid sleeping even though i need so much of it. i'd much rather nap later in the day than try to sleep through the night
