When you're a passenger on an airplane, you are told that in the event of a change in cabin pressure, you should put your mask on first and then assist your children. You can't help them if you are unconscious. A similar principle applies with your day to day health. Mothers tend to put others first. While this is admirable in one sense, it is not a good practice in the long run. You cannot strike a balance between your needs and the needs of your family if you are constantly run down. Stop abusing your body.
