I should also be in May!!!
Probably my best advise would be to log on to ObesityHelp and read some of the posts. Look at the before and after pictures and think about the statistics and how they are in your favour for better health. My Hubby isn't the least bit interested, really, I mean, he supports this, but I don't think he really understands. I have some medical background so I think he just figures I know what I am doing. Hope this helps and your wife can find some peace in my suggestion. I don't know if she is so inclined, but prayer can be a powerful way to find peace. As stated in the poem Desederata, "No doubt the world if unfolding as it should" or something like that .
Good luck.
