Is it normal to distance yourself when caring for parent with Alzheimer's?

Sometimes I feel I'm being cold to what she wants( not needs) during her spells of depression. Sometimes just plain don't know how to act or what to say. I can't make other people do anything to sooth her(family) so I kind of have to be cold but doesn't make me feel right about it. What should I be doing?
She lives with me and my husband.

I think this is a self preservation mechanism. It's not that you are cold and uncaring, but dealing with a loved one who is suffering from Alzheimer's can be very difficult and frustrating. Especially in the times when the person can be quite lucid and know their surroundings and other times there is no recognition at all. There is no set of written rules to help you know what to say or how to act. I am sure you are doing your best to cope in this very difficult situation. Of course there are help groups available for families of people who suffer this problem. I am sure if you looked it up on the net you could probably find one in your area or contact your the social worker involved in the case of your relative. It may in fact come the time when you will not be able to look after her and she may have to go into care and that is something one also needs to consider, at what point to do you realize that keeping her at home may not be the best thing for her or for you and your husband. I hope everything goes well for you.
