There's a feature in the LA Times today, June 11, about caregivers and the mental and physical effects of caregiving.
It mentions a useful organization, Caregiver Resource Centers. There are 11 of them in California, serving about 14,000 of the 3.2 million caregivers in the state. To contact one of these centers, go to http://www.californiacrc.org/californiacrc/jsp/home.jsp.
Nationwide, there are probably 46 million caregivers.
Getting help can cut the high level of depression among caregivers by 50%.
