Way to go, Scoot!!!! I know how you feel. I've let myself get kinda out of shape this past winter, and I'm trying to get back in shape, hopefully, by June.
One of MY biggest problems always involved my self-image. You see, my big sister has a MUCH faster metabolisam than me, and she eats like a horse, but is as skinny as a toothpick. I know we're made up of two completely different body types, but I can't help comparing myself to my tall & thin sister. A few years ago, I lost ALOT of weight, but was heartbroken when I tried to borrow one of my sister's skirts and found out it still didn't fit. It took me a few years to finally figure out I'm never gonna look like my sister. I'm not built that way. I'm short and squat and that's the way I am! (Of course, my sister always likes to point out that I'm a bit more.....umm...."full-figured" than her in some areas, which SHE had image troubles with for a while, too! Which REALLY suprised me when I heard that, lemme tell ya!)
ANYHOO, whatever your body type, be happy with yourself. And don't try to make yourself into anything you're not, just because that's the way you feel you "should" be. I was in GREAT shape last summer, and I STILL couldn't fit into my one of my sister's skirts! (It had gotten too short for her!) Not everybody's meant to be a size 2....So, don't be dissapointed w/yourself, if, even after all that dieting and exercise, you're STILL not a size 2!!! (Like *I* was.) Not everybody's gonna look like that. Took me awhile to figure that out.
