Welcome
I agree that a positive attitude will definitely help you out. I can see that things are tough for you right now and a positive attitude will be difficult for you, but just remember that things happen for a reason and we are never given more than we can handle.

When you wake up in the morning, smile and tell yourself how fabulous you are and that everything will turn out just as you want it, in regards to your weight loss. I've recently witnessed (on Facebook) that a friend has battled cancer and won.
The mental battle is the toughest of them all, but you will be stronger once you come through the other end.
If the scales are something that you are unsure of, then my advice is to stay away from them. Don't be constrained by the numbers because they won't help you right now

Weight loss can be seen in the mirror and it is reflected in your smile; a smile that knows you are achieving. Stay away from the scales, put them in the garage if you have to, and concentrate on the foods you eat. If you have a binge, don't worry about it. Weight loss is a lifestyle and none of us get it right the first time! In fact, this month has been a bad one for me in regards to my foods (too many birthday's and wedding's!), but I know that if I keep going I will achieve my goal.
You can do it, you just have to believe in yourself just as we all believe in you. By coming here you have taken the first step
