In many families, caregiving does not arrive with a discussion or a plan. It simply lands on one person’s shoulders and quietly stays there. The default caregiver often steps in out of love, proximity, personality, or necessity. Over time, that role can turn into a full-time responsibility that reshapes identity, finances, mental health, and family dynamics. Understanding why this happens, how burnout develops, and what professional solutions actually help is essential for protecting both the caregiver and the person receiving care.
