Newly Wed Who Needs Motivation

I have been married for a year and a half and ever since receiving our wedding photos, I had tried ever fad diet and detox pill. I still can not look at my wedding album without feeling awful about myself. I am hoping this will finally work out for me. I had totally been in denial. I weigh 185 and I am only 5'4. I always say to myself that I really want this, but for some reason when the time comes to make a food choice or I have time to work out I don't. I real need some motivation to get my feet off the ground.
