Recently started waking up after just 6 hours of sleep and can’t figure out why

It’s been like this for over 2ish months now I think. After a hospital stay (I tried to OD on Tylenol). I always wake up after only 6 hours and going back to sleep has been hard, no matter when I go to sleep. I saw a video of a guy talking about his experience with pancreatic cancer and that this was one of the symptoms and now I’m seriously worried. I’m 25M if that helps
