At least in my case. I used to do this because a, I had a looot of weight to lose, and b, because I thought it made me a hardass. It doesn't. The truly disordered of us ARE hardasses, and I admire them for coping with it with all the grace and beauty they do, because they are beautiful you know. =] And I hope they know it too.
Me, now, I do this because I enjoy the sense of power and accomplishment I feel when I lose a few more pounds, inching towards my goal. Just the thought of shunning something like food--something essential to life, just makes me feel like i have true power over something in my life. =] And I love that feeling. I love the feeling of hunger, and most of the time I don't get to feel it enough.
I'm just a selfish girl with self-esteem issues. That's all. That's my only identity.
I just felt like getting that out there, because I know most of you are thinking 'wannabe' when you read my posts. =] I love this, and I'm getting better at it. And if it keeps making me happy, I'll continue. =]
