Written by While many of the tasks assigned to a caregiver are physical in nature, they also provide emotional support to the individual they are taking care of. Listening is one of the most important things a caregiver will do for your loved one. Caregivers listen to their patients, have conversations with them, and provide the overall emotional support that is needed. This emotional support may be lacking without a caregiver as taking on the task personally can stretch you too thin with your other responsibilities.
