I could say a million things to motivate you to live a healthier life, but the truth is... Only you can change your mind set and your attitude. You need to find something you want more than that donut or pizza or sitting on the couch and relaxing all day. (Those are the things I loved) That way when that donut is in front of you you can say "no because I want something else more." I promise eating healthy gets easier and exercising becomes fun. But it takes a long time. Stick to it and eventually your attitude will be "when" instead of "if" I reach my goal.
GOOD LUCK! Don't be afraid to talk to me personally. I'd love to hear from you.. If there is anyone out there.
