I highly recommend The Caregiver Helpbook, Powerful Tools for Caregivers. It's a handout if you can go to a Powerful Tools for Caregivers class. If you can't, it's available online from Amazon and maybe others.

The class and the helpbook do just what the title says, it gives you powerful tools to help you in your caregiver role. It includes helping you to develop action plans for each week to help you accomplish your current objectives. An important part of it is to help you take good care of yourself. That's essential if you want to continue to be able to take care of your loved one.
