Old, Disable and Fat

I was into bodybuilding as a lot of young people were back then and I was getting there. I was not too bad but not too cut up at 30 years old I had a 58" chest 191/2" arms 34 waist you know the works. Then came the divorce and the feeling sorry for myself what did do wrong and missing the kids. But know remarried very happy got the kid back or should say the kids came back. Now 15 years later fat and wondering what happen I know all about dieting and exercise but I have no "get go" and then a month ago with the help of my wife I got the "get go " back. I can't do to much on the exercise because of my limitation's but try but the old diet which is "self made" from reading about different stuff about dieting is doing great droping weight a little fast but that always happens at the beginning with what I do (upgraded old diet) times is a changing I went from 335 to 305 from 3/1/09 to 3/29/09 not bad but we'll see next month.
