How to determine Good Sleep?

I feel pretty close to giving up on the CPAP stuff. There is actually a question as to whether or not I even have sleep apnea. My current doctor at Jefferson is running a sleep apnea test again for me at home to make sure I even have it considering the last doctor diagnosed me with narcolepsy and was a complete and total moron.

I go to sleep exhausted. I wake up exhausted. By 12:00 p.m. I'm exhausted and want to take a nap. By 2:00 p.m. I need to take a nap. After I wake up from my nap. I'm still exhausted. And remain exhausted and in limbo between wanting to do things and wanting to nap again till I go to sleep again. This is everyday. Regardless if I get 5 hours of sleep or 8 and 1/2 hours of sleep. Regardless, if my AHI is 3, or less than one. It does not seem to matter. And now I'm starting to even wonder if my issues with chronic fatigue have anything to do with sleep at this point.
