Morning Polly,
The negative attitude and bashing yourself needs to be put aside. Take the first steps in changing your way of eating and your way of life. This isn't a yo-yo diet it's commiting yourself to this way of life. You know it works you've been on the other side, it's something that takes one day at a time little baby steps. I've lived this life style for at least 5 years and I struggle every day. You need to push yourself, excercise even when you don't want to...get a buddy.. if not by your side find someone in here that will help you, give u a lift when u need it and a kick in the butt when you slack off...I have 2 people at work and we help each other..I go to the gym 3-4 times a week at lunch time and theres days when I don't want to go and guess what.... they make me....
I also lead and Exercise Challenge here...The Squat Challenge...you should check us out..look at the Excercise Challenges and maybe you'll join in one of them...it does help knowing were also out here,doing the same thing as you are. I get down alot on myself..but what does that do?? Not a darn thing, If I could lose weight by complaining and crying ..geez I'd be thin as a rail..lol..just put your chin up...stop hiding behind your cardigan..and get your butt moving!!!
Good luck
Char
