A woman who fought back after the sudden death of her 26-year-old husband, on the third anniversary of her mother's untimely passing, is sharing her advice with women for how to be strong. Amy Morin, a psychotherapist-turned-writer, has written a new book, "13 Things Mentally Strong Women Don't Do." "I wanted to show how women and girls are treated differently," she told Inside Edition. Her first piece of advice is to not compare yourself. Her second tip is to not overthink things.
