Well...you are to be commended on your self-awareness. You are fat, and out of shape, and you realize it.
Of course, that's easy to fix, given some time, and patience.
Sooooo....fix it. It's just that easy.
If you don't like yourself now, that's easy to change. You have the power.
As Tony Little says, "Just do it."
At least you have the courage to show yourself, and to admit your weight is out of control.
Surround yourself with experts, quit putting yourself down, and take charge of your weight. It IS that simple.
Today IS the first day of the rest of your life.
