My mother-in-law said this meal was for me! The baby is for me! I really want to scold her! Also said that I didn't get married, didn't have children, didn't wash my husband's clothes?

This kind of mother-in-law is unbalanced, feels that she has paid too much, and is worried that no one will honor her when she is old. Don't argue with her. You have lived with your husband all your life. Let her say anything in the future. You can go in one ear and out the other. If you really can't stand it, live separately, out of sight, out of mind.
