Take time with your appearance every day. When you get up, make a point of getting dressed, fixing your hair, and putting on a little makeup, if you like it. Pamper yourself with a facial, a new hair style, or something new to wear. Looking good helps you feel better about yourself. Get some exercise every day.
Many people find that exercise has an antidepressant effect.
Take a brisk walk every day with or without the baby. Nurture yourself as much as possible. Take long bubble baths, get a massage, ask your partner to hold you, spend the afternoon watching a video or reading a light novel. Spend some quiet time in prayer every day, or visit the Blessed Sacrament. Make an effort to spend time with other adults.
