bytheway, Women get brainwashed about what is an 'acceptable' size, an 'acceptable', look. This look is an identikit look regardless of size, shape or genetic inheritance. If women do not meet it they are led to believe they are worthless. This is the vicious circle you have been sucked into
Forget about 'acceptable' looks, weight, or anything else. Learn to stop hating who you are and instead accept yourself for who you are, a lovely woman who has a husband who loves you and supports you. Forget about diets, eating plans, eating more of this and less of that. Just eat what you want when you want it and stop when you feel you have had enough. Throw away every diet and calorie counting book in the house, Stop looking and searching for dieting and weight loss websites. Then prepare a meal of food yo really enjoy, eat it slowly and savour the flavours.
To begin with your body and metabolism will be in utter confusion after years of different diets. So it will take a while for it to start responding normally to food. Take your time, but eventually you will find an eating pattern that suits you and you enjoy. It will probably mean that you are eating much less than at present.
Your problem seems to be more in your mind than in the body. Have you considered counselling or getting your doctor to refer you to an eating disorders clinic where you can get proper psychological support?
Whatever happens, stop fighting food and start enjoying it. Take pride in who you are and what you are and refuse to be defined by other peoples standards.
