Eat, sleep, work?

I really don't know what to do. I am so tired ALL the time. Lately I just have zero energy. The doctor is messing with my meds again to try and fix me. I guess I don't sleep well, but something is going to have to give. I have to go to work, I have to do the household chores, I have to take care of the dogs, I have to exercise, blah, blah, blah. I do make time for fun, but it is sad when my "fun" is taking naps and doing nothing. Is this all there is to life? Eat, sleep, work? I surely hope not.
