Getting rid of the scale or at least put it away where you dont see it everyday like I do and pull it out only once a week to weigh in. I do this on Mondays. You will seee a fluctuation of numbers if you weigh in every day and that can be discouraging.
Second, you sound like you already can admit that you have a problem, unlike in the past and that is your first step. Food is an addiction just as is alcohol, drugs or anything else. So admitting your problem will allow you to take the steps needed to address it. Just like AA's 12 step. The philosophy to that can work for anything.
Support from your husband would be helpful but ultimately it is up to YOU. Only YOU can make the changes that will give you a healthy mind and body. The willpower to say no is hard sometimes but you have to be stronger than the urge. It takes time and we all slip every now and then but you just haev to say, OK I slipped but know I was wrong and now I will be back on track.
Coming here and posting will help you, I know it helps me. Especially knowing that all these women and sometimes men, know exactly where I am coming from because they have been there or are there now.
Type out a insirational saying and tack it to your mirror the fridge or wherever else you will see it. When you read it read it out loud everyday. Its a great way to insire yourself and enforces auto suggestion. Keep your thoughts possitive and you will get possitive results.
Also if you start slowly with some sort of daily physical activity even walking down to the end of the block and back, you will start to feel better. As you start to feel more confident in yourself you will soon discover that your activity level will go up. Anyway, didnt mean to sound like I was preaching, but sometimes we need that too. I KNOW you will find your path and do just great.
