Since Giving Birth, I Rarely Have Sex, And I Feel Worthless. I Only Gain Pleasure From Eating. Normal?

I never knew that becoming a mother would take away who I was so completely. Not only did I gain weight, but it seems the only pleasure I can get is from eating. My husband and I rarely have time for sex except when the grandparents watch the baby. Even my mother, who spoiled me, doesn’t even believe me when I tell her I feel sick, until I throw up. I don’t have time for anything, and although I love my baby with all my heart, I feel worthless in my life and I can’t do anything about it. Anyone with this kind of experience have advice on how to get through?
