I agree with kt going with number 2.
Binging is you trying to cover up your true feelings by feeding your soul and body with food, things that make you feel better. But - food only makes you feel better temporarily. Trust me, I know.
Have you talked to your husband about how you feel about things?
Maybe start getting yourself more involved in the community, go out and take more walks and get fresh air, find a hobby, work out at an all women's gym.. take time out for yourself, the time you've need and deserve. Remember all of the things you used to do before your kids and husband, and maybe start up one of those old passions again.
I wish ya luck.
