Chronic Fatigue?

I'm not so much a hypochondriac as I just want something I can act on. If it didn't take two full pots of coffee and some non-amphetamine uppers just to keep myself awake for ten or twelve hours (and that's with a nap) I'd admit to being lazy but this is getting ridiculous. It reminds me of the comedian Larry Miller who once said "My father had three jobs and went to school at night. If I go to the cleaners and the bank in the same day I need a nap." The worst part of it is it actually feeds my fears and insecurities. When I have energy I just put stuff out there because I have the strength to withstand whatever criticism that might come along but when I'm this tired constantly the thought of someone finding flaw is devastating so I just don't take any risks by putting anything out there.
