Caregivers should find support before becoming overwhelmed by the burdens associated with taking care of a patient with a chronic illness, according to a human development and family studies expert. “You have to take care of yourself to take of others,” said Kristin Litzelman, a professor at the University of Wisconsin-Madison. “If you’re not taking care of yourself, there’s no way you can provide help to someone else. You won’t have the physical strength or the emotional strength.”
