Your post is heartbreaking

I feel horrible that your husband can not find it in himself to be supportive, rather than seemingly cruel. There are ways to say and handle things, and ways to not.
There seem to be a lot of issues to address in your post. As I've found with a lot of people, a healthy
inside is the first step to a healthy
outside. Have you been to a doctor to discuss your feelings? Depression (no matter how mild) can lead to an unhealthy weight gain, and the feeling of helplessness to lose weight. Also, have you had your thyroid levels checked? Sometimes getting your vitals in thyroid/hormones/cholesterol is a great place to start. Afterward, you can make a healthy plan
with your doctor.
And you shouldn't feel that food is your enemy! Food can be a wonderful experience, when used correctly! Raw foods, vegetables, fruits, whole grains, lean meats.. I've personally found ALL of these much more flavorful and enjoyable that sweets and junk food!
Please remember.. Weight loss should always be for yourself, not to please a partner, coworker, or other outside pressure. If you try to become something for someone else, it tends to be a very unsatisfying experience.
GOOD LUCK!! I hope you find the support and information you're looking for!
