Lighter But Not Smaller?

I've been trying to research this on the great wide web, but I'm falling short. There just isn't info out there that relates to what I'm going through.

See, I'm technically lighter right now than I've been my entire adult life. I weigh less than I did in high school and in college, and I'm losing weight week by week with Weight Watchers.

But I'm not SMALLER than I was in high school or college. At least, I don't think I am. I remember wearing a size 16 during the summer between high school and college comfortably, and now I can squeeze into size 16 jeans but they're definitely not as comfy as my size 18s. Like, I'm not complaining. The last jeans I bought were size 26 and I immediately tore out the tag, cut it into tiny pieces, wrapped it in toilet paper, and flushed it. I didn't want anyone else to see my size, and I got sick seeing it myself.

Right now, though, I don't feel my smallest. I've read that a lot of it is psychological and that it will take some time before my mental image catches up to my actual reflection in the mirror, but that's bullshit. I mean, yeah, I have a pretty warped idea of what I look like. We've established that months ago. But I am seriously bigger than I used to be, even though I weigh less. It's not in my head.

I have this really cool belt that I only kept around in case I could use it for a craft project--I bought it when I was 18, wore it for a year or so, and then grew out of it. It's been in my craft supplies for the past decade or so. I found it a few days ago and tried it on--it barely fit around the smallest part of my waist, which is way higher than I would have ever worn a pair of pants when I was 18. It was several inches from closing around my hips, where I would have actually worn it. So what gives? How did the belt fit when I weighed more than I do now, and it's not even close to fitting now that I'm lighter?

Is it just age? I'm so much fucking older now...are my organs sagging?! At age 31, are my intestines getting fat while I'm losing weight everywhere else? Did I just lose all of my boob weight, and now the weight has redistributed to my stomach? Yeah, that's a lovely image. Just what I want. Work my ass off to lose weight, only to find myself with no tits and no ass and a big, dumpy stomach hanging out in front. Or do old people just look bigger at the same weight? Is it possible that I've lost so much bone density that I will have to lose a lot more weight to be the same size? Like, I'm thirty-freakin-one. I shouldn't have osteoporosis, right? And I was a cheesetarian for a decade...I think I devoured more calcium than anyone else in the world. If anything, I should have calcium formations on my bones.

Ahh. This is just another of those obnoxious weight loss things that I don't fucking understand. I'm still not quitting. I'm still losing weight. I'll keep going until I'm happy with my weight and my size. But really...what the hell? It doesn't make sense, and I hate when stuff doesn't make sense. Maybe I should have gotten a biology major instead of a worthless Women's Studies degree...
