My 96 independent uncle lives alone. He has dementia and recently was told he has terminal cancer. His personality is up and down and for the most part I could just walk away when he got out hand. His needs are increasing but he does not want outside help. I am not sure what to do? I am his main caregiver but I am limited myself and can not take care of him on a full time basis and barely on a part-time basis. Needs to focus and direction.
