Here I am at the beginning of my journey. For years I've felt like I'm wearing a fat suit and the healthy, fit Stacy is trapped inside. That's why I'm so excited to have been chosen for this opportunity. Last Sunday, it was slow at work, so I was reading an old issue of SHAPE. I got to the Weight Loss Diary page, looked at the column, and said out loud, "Oh my gosh, that's going to be my photo and my story right there on that page!" It felt surreal and too good to be true. And then immediately I thought: What have you gotten yourself into?
