I'm so sorry that you are on this Alzheimer's journey with your husband right now. It has to be incredibly lonely. Please know that this community is here for you when you need us.
Additionally, have you looked into support groups in your area. I've talked to quite a few caregivers who find being able to talk to others in the situation very helpful. The Alzheimer's Association, which has local chapters all over the U.S., offers them. They also have a hotline, staffed 24/7 with professionals who can help you connect with these resources and others 800.272.3900. I know of people who have set up support groups independent of an organization as well. May I ask what area you're in?
