Do I have a slight form of narcolepsy?

Sometimes I find myself FIGHTING to stay awake during the day. Even when I had a full nights rest. It even happens when I'm driving. Its very scary. I try everything to fight it, turn up my radio loud, put down all my windows, singing, everything! But my eyes just want to close & there's nothing I can do to stop them on my own. I have to call someone & make them keep me awake just so I can get home safely. But It even happens when someone is in the car with me. I don't know what to do. I even try holding my eyes open with my fingers, it doesn't work. I feel like I don't have any control! What's wrong with me? And what should I do about it?
