I've been lurking here for nearly a year now while working on losing weight & improving my health.
I owe this board a lot of thanks. Whenever I got discouraged with the process or felt lonely, as I were the only one out there struggling with myself, or whenever I was proud of myself for making sure I exercised despite adversity (snow, an overly scheduled day), I'd get on these boards & read the posts. I already feel like I "know" some of the members -- but it's been a one-way relationship, like with actors in a TV show. So I feel like I need to get in there finally & participate, rather than watching. I need to offer something back.
Like many here, I've lost weight before -- when I was 30, I dropped nearly 90 pounds. I started out healthily but became obsessive about it & developed anorexia. I vaguely sensed something wasn't right, and I tried to respond to my friends & family's concerns by eating normally. But when I did, I seemed to have no concept of moderation. I lost control & became a bulimic binge eater. I tried vomiting, but it grossed me out, so I began was over-exercising for two or three hours a day. I remember going on a trip with a friend. (Which was fraught for me, because I feared I'd have to go without exercising.) We were in Chicago, shopping that afternoon, on a street corner, waiting for a light to change. I was so fearful of being still & not getting enough exercise that I was marching in place, moving my legs. My friend looked at me in a kind of amazement & fear & said, "Can you stop that please?"

That's when I realized how crazy I'd become.
Anyway, through therapy, and by making a better life for myself, I overcame the binging. But I stopped exercising & put all the weight back on, plus more.
Now, over 10 years later, scared by a diagnosis of pre-diabetes, I've again lost 100-plus pounds. I did it slowly & sanely, over more than 18 months. I have just a few more pounds to lose to hit a healthy BMI on the charts. But I'm trying to monitor myself carefully -- my mental state, I mean. I do NOT want to become obsessive again. I want to make exercising & eating healthily as sane an act as brushing my teeth or showering. The way I see it, there's a difference between washing one's hands a few times a day to avoid germs & the compulsive hand-washing that makes them chapped & raw. I want to stay on the SANE side of the line this time.
(I didn't mean to write so much but I think looking back to our personal history is VERY important in our weight loss journey, and mine is fraught enough that I had to keep it in mind & watch myself to make sure I get it right this time.)
