Summarize:

No one controls your worth and self-esteem except you.  While you may seek approval from your husband, understand that he can't change how you feel about yourself, but you can.  While getting words of reassurance from your husband can help to boost your self-esteem, don't rely solely on him to determine how you feel about yourself or your appearance. Practice building up your self-esteem and self-worth.  Consider saying these words of self-affirmation: "My self-worth is not determined by the number on the scale," or "I am more than my appearance." Don't fall into despair when your husband says you're fat.  If you already have certain goals about your body image, keep them going.  Avoid letting your husband control the goals that you have for your health, your happiness, and your life.  Determine what goals feel right for you about your health and body image. Determine what makes you feel special and appreciated. Advocate for yourself and your needs. Find ways to feel good about who you are beyond what your husband says.  Think about what activities make you truly happy. If your husband’s comment didn’t strike a nerve, deal with the name calling rather than focusing on the bit about your appearance. When you've been hurt or insulted, you may feel like you want to retreat or fight back. Rather than expending so much energy on negative thoughts and feelings, focus on what makes you feel positive about yourself and your life. Take time for yourself to do these things:  Reflect on the positive things about you and your body.  Write in a journal about what you like about yourself. Choose at least 3 things to write about. Do activities that are independent of your spouse or family.  Have a night out with your friends.  Go out and  explore a new place.  Cross something off your bucket list. Focus on activities that restore a sense of peace and love for your body.  Consider gentle yoga or meditation.  Get a massage.  Do things that make you feel beautiful and refreshed.
Remember that you determine your self-worth. Figure out your goals, regardless of what your husband says. Practice self-care.
