My father has dementia and is very loving sometimes and very horrific other times. I cannot deal with living with him and his two personalities. It seems like the nasty personality is coming out more and more. He hates my husband and only wants me here. I feel like I am losing my mind. I have a life that I have neglected for the past year to take care of him. I am an only child and it is tearing me apart. But, it has to be done. He is, also, getting very weak and I cannot lift him on the days he cannot walk. Also, will I have to obtain guardianship to do this? He cannot even sign his name anymore. I have Medical POA.
