i hear ya, sistah! well, i did used to be slender, but that was a long time ago<G>.
don't fall into the 'i'll be good' or 'i've been bad' trap. it's sooooo very pervasive. changing your body image, your eating habits and your patterns of self-sabotage is a long trip. you understand it intellectually a long time before you're able to make permanent changes.
just slowing the pendulum is a great start. you will still likely swing back and forth, but you can make the extremes less drastic. try not to think of it as 'anything goes' and 'being bad' versus 'behaving' and 'being good.' part of the problem is that we tend to feel that if we've blown it one day, we may as well write that entire day off and eat ourselves sick. that's like getting a speeding ticket and thinking 'well, i've already broken the law today and got caught. might as well drive like a #@$%^ idiot for the rest the day now!'
if you overeat or over-sugar, don't waste time beating yourself up. you now have the opportunity to get through the rest of the day, or the next hour, or the next 10 minutes, drinking water, and choosing to fuel your body with nutrients that will energize and nourish it.
that doesn't mean you'll never overeat unhealthy stuff again. but you don't have to do it NOW.
if you talked yourself out of working out today, you can still do something. do some bicep curls during a commercial. walk up and down the stairs 2 times more than you have to.
drink another glass of water.
small steps, hon.
we'll make it!
