Rose, being a care taker by yourself is overwhelming never mind someone with dementia. None of us are meant to do it 24/7 it is too much. If you can get the help of a social worker to help you with shopping, cooking, bills or etc. you will find it will help you mentally tremendously. Also there is counseling for seniors dealing with this situation. I took care of both my parents so i know how you feel and what you are going through. (((hugs))) tc
