Need more than 9 hours sleep

I ended up napping from 4:30-8 yesterday afternoon.  Then I couldnt' fall asleep until 1AM.  I still got up at 7 this morning.  Then I had a nap from 2:00-4:30.  It's 9 now and I'm ready to sleep. I'm trying to get just 9 hours at night without a nap but it seems my body can't handle that.  I need more.  It's frustrating.  What are you supposed to do when you're sick?  You can't commit to much because you don't know when you will have energy.  But if you have nothing to do you just get worse.  IDK - see the therapist tomorrow, maybe we'll come up with some solutions.
