My first thought was that it was neurological. Mainly cause of the sleepy eye and fatigue. I would see a doc.
Have you seen a doctor about any of this? Sleepy eye, blood rushing - couldn't say. I think I'd want to be evaluated by a neurologist, and if they think so, get a sleep study. There are things that commonly make one tired, like diabetes, thyroid, anemia. And if one sleeps 8 hours and is still tired, if nothing else shows up, maybe a sleep disorder should be considered.
oh and I get about 8 hours of sleep every night still feel like ****
