SkinnyLady, this is totally normal!!!
I just want you to know that...you might want to post about this in the Maintainer's forum and get their perspective. They'll tell you all about body image and the work you have to do in your head to match the work you are doing on your body.
I went from feeling incredibly skinny after losing about 50 pounds because I was so much smaller than I used to be, to feeling really fat after losing about 100 pounds because I was so much bigger than I wanted to be!
How crazy is that? But it's honest...and we really do have to work on seeing ourselves as we are and not in comparison to our old selves or our selves-to-be or to anyone else, for that matter. It's hard to do!
One thing that helped me immensely is focusing on getting healthy rather than just on losing weight. Then, even on my 'fat days' I could still think about the change in my cholesterol, the improvements in my various maladies, and how neat it was to be able to move my body in ways I couldn't before. Working out does this for me, too. Seeing that I can lift a heavier weight, that I can get through a Jazzercise routine without feeling that my head will pop from overheating, or that I can do yoga poses now because my fat isn't in the way, helps me feel so much better about my body and myself.
You might want to read a fabulous book: "Passing for Thin" by Frances Kuffel. She talks quite a bit about this issue and how she dealt with it while losing more than half her weight. The book is hilarious but has tons of truth at its core. I really, really enjoyed it!
Another issue here is that losing weight doesn't guarantee happiness, and it DEFINITELY doesn't take away anything that was bothering you before! In fact, I liken losing the weight to melting the ice off of things after winter. You just reveal what was there before and bring it to the light! Your problems, issues, and feelings are now exposed and hard to pretend away. You have to deal with them and find a way to do so without overeating (which didn't work anyway, did it? They're still here...). I know that therapy has helped me immensely in this area. I knew that losing my weight wouldn't guarantee a pain-free life, but I was still stunned when I came this far and didn't find my life easier.
It's hard not to feel that when you change this much, your life should too...
for you, SkinnyLady, and for CE, too. It's a hard journey, but at least we're here to get through it together, eh?
