My seems to whimper and whine about silly things- not wanting to do things (which she doesn't have to) like cleaning the kitchen floor, or washing clothes. She even gets "whines" or pouts when we have things to do- even going to church functions. My husband says not to give in to her and do what se wants, but I often decline invites b/c I feel guilty and stay home with her.
Still, you need to get out yourself. An evaluation by a doctor seems in order (for your mother). Anxiety and/or dementia may be part of what is going on. Once you know what is causing this, medication may help, or even some respite care so someone can stay with her while you go out.
Take care,
Carol
