Monitor your mental and emotional health and watch out for prolonged sadness, anger, resentment, sleeplessness, alcohol abuse, and anxiety. See a therapist if need be. Call on relatives and friends to relieve you and, if you can afford it, hire someone to come in several mornings or afternoons a week. Don't be a martyr. Your role is very difficult, and it will help you get through the tough times if you can share your experiences with people who are going through similar experiences.
