Yes, its time you see a doc about this problem it could get worse, or you could just have a sleep disorder like sleep apnea or another one. I have sleep apnea, i used to be up all night and sleep in the day until i had a test done and i sleep with a sleep apnea machine now which changed my whole sleep cycle for the better. now i sleep for 8 to 10 hours a night and wake up refreshed more than i used to. I never did feel like i had enough sleep and wished i was dead every morning. I hated waking up in the morning, i'm am still working on that, but after my first cup of coffee in the morning it isn't as bad.
