If your mother is tired of trivial things in life all day, such as housework, it must be that you and your father do too little and ignore too much, which makes her lose herself.
If mom has enough time to do facial and nail massage and go shopping all day, then there must be friends around her who make her feel better than herself. Don't mind a woman's vanity too much.
Are you and dad introverted or do you seldom communicate with your mother at home? If mom is a full-time wife, it is easy to feel depressed and resentful!
