WARNING: Tough love herein.
A lot of this just has to do with being in your 20s. I've been there: it's an emotional time. For me it was a VERY emotional time. As you get older, you often become much more comfortable in your own skin. It's one of the things that makes aging something with which I can deal.
From what I know of you from your posts, though, I've got to say that I don't think you have really committed to making a lifestyle change. And, until you do, you won't lose the weight you want to lose. I know: I stayed at 129 way into my 30s because I just couldn't get my head in the game and commit to making permanent changes.
I agree with everyone who says to love yourself no matter what, but I also completely understand the desire to shed those "extra" pounds. And you won't do that effectively until you accept that you have to change the way that you eat. It's hard to do this when you're already thin by everyone else's standards. I know: I was a size 0/2 before I lost weight. So, as much as I wanted to lose, a part of me knew I didn't have to—and that made committing difficult. Eventually, though, I just said, "Screw it! I want this!" And I did commit. You can, too.
Please understand: I'm not saying you need to lose weight. But I have been where you are in your head. And I'm telling you I stayed in that place well into my 30s. Was I happier? Yes. Did I cry as much? Oh, no. Being in one's 20s is so hard. But I still wanted to be thinner in my 30s. I craved it still. And as much as I had come to accept who I was, I wanted to be an "even better" (in my eyes) me. So I had to make a change—for good.
You can't have the big pasta meals regularly. You can't have alcohol regularly. You can't have a lot of things you love regularly and still get where you want to be on the scale. It sucks, but it's true. You have to make a choice: party like it's 2010 or be the person you want to be, in the body you want to have, in 2011. I'm not saying you can't treat yourself sometimes. But you have to find balance.
If you can commit, the stress will fall away. It truly will. It's trying to live in two worlds—the one world where you compulsively watch what you eat and drink for a few weeks and the other where you eat and drink whatever you want for a few weeks; the one world where you count every calorie during the week and the other where you go crazy on the weekend; the one world where you eat little all day and the other where you eat way too much at night; the one world where you low-carb and the other where you binge; the one world where you try to keep up with your friends in the celebration department, and the other world where you secretly hate yourself later—that causes so much stress. You can't lose weight and keep it off this way. And you can't find peace, either.
I've all but starved myself before. When I was a freshman in college I ate one small meal a day for about four months.
I've also exercised all day and into the night for months and months on end.
And, in between these feats of insanity? I ate "too much." Too much, that is, to stay under 129. And I hated doing it. I've always been thin to everyone around me—and that made it easier for me to yo-yo instead of learning how to eat right and maintain a loss. But I still hated the fact that I was always either depriving myself or eating more than I ought for my goals.
Eventually, you really just have to commit and do it right. Don't overly restrict and don't go haywire, either. Adopt a healthy mentality toward food. And when you do—if in fact you find you really do want to lose the weight (because, again, no one is suggesting that you need to)—then you will find balance. Then you will find yourself.
Is everything going on with you about weight loss? No. It's about being in your 20s. But, if you are anything like I am, it's about the weight, too, and the feeling of being out of control, of not being able to achieve your goals. But you can. You. Just. Have. To. Commit. To. Doing. It. Right. And. For. the Long. Term.
*BIG!!!!! HUG* I have been there, girl. I understand.
