wish i would have posted what you did back in october 2009. but i didn't. i had lost 160 lbs, and got "bored" i too know it is a mental issue with me. sooooo, i gained 5 lbs, then 10, then 50, then 100, and before i knew it a mere year later i had gained it ALL back plus 3 extra........if only i had stopped at 5lbs.
this time i am seeking help for the mental aspects of my eating disorder.
you said it yourself, and if it seems like a mental issue for you too, please call someone in the morning, and start working on it. you have come too far. and believe me, it is not easy taking a backslide like that.
you know you are in a dangerous place right now, i'm guessing that is why you have posted, please please take the steps you need to take to move forward....it is all a part of the process.
