In a way, full time caregiving for a family member with a disability is a kind of disability itself. While the impairment is not in the caregiver's body or mind, it certainly does limit many major life activities.
And, while there are some organizations and online support groups to help caregivers and a few that even provide respite care, it's often difficult for the people who need them the most to find the time to take advantage of them.
But if they can squeeze out even a few minutes a day, there are some books that might be helpful. The devotional by Tim Hansel I mentioned in my last post is only one of many, including some by Joni Eareckson Tada. Both those authors have disabilities of their own.
If they have more time to read, there are lots of other books that can help caregivers cope. Cecil Murphey's My Parents, My Children has encouraged many people taking care of aging parents, and there are many books about specific disabilities written by people who have personal experience with them. Sometimes just knowing other people have had similar things to cope with can be encouraging.
And many libraries provide delivery of books for people who can't go out and get their own.
