Narcolepsy is. Usually an unpredictable dropping asleep, but sleep disorders can run a spectrum from oversleeping, to inability to fall, or stay asleep. The other answers mention sleep apnea as a cause of chronic lack of sleep, what you have sounds like excess. Find a sleep specialist, neurologist, psychiatrist.
Excessive sleepiness. Your level of sleepiness is abnormal and likely represents a sleep disorder. I would schedule an appointment with your primary care physician right away. An appointment with a sleep medicine specialist may be needed.
See your doctor. There are certain conditions such as obstructive sleep apnea and others than your doctor can test you for. Often times there are solutions that can make a significant impact on your sleep habits.
