Health, or lack thereof?!?!?!

So, as I sit at the computer to do bookwork today, I can't get over the fact that there's no ambition or energy coming from me whatsoever!

Over the last number of years, I've had many doctors appointments, physicals, blood tests, etc. I've taken vitamins - even prenatal ones, when I'm not preggers! I get a good 8 hours sleep pretty much every night. My diet is not fantastic, but I eat my veggies and try to watch my portion sizes, etc. I even went to a gym for a year and GAINED weight, and stayed just as tired!

So, you tell me!!!! What on earth am I doing wrong? Why do I never feel like doing ANYTHING?!?! I look around at all there is to do, and I feel so tired and lazy that it's not funny! I've asked people all over the place for tips or ideas... I'm not finding any that are working! So, I'm up for any new ideas... As long as they're not too far "out there" or expensive, I'm getting close to being ready to try anything!
