There are not many things to be sure of in this life but you can definitely be sure that you are not alone. Have you thought about you and your husband going to a marriage counselor? That may help you. Also, you say that you are embarrassed by your personal appearance. Maybe if you make a concerted effort to change whatever it is that you don't like about your appearance it will help both your own opinion of yourself and your husbands as well. I wish you the best of luck.
