My dad is suffering from dementia and its so hard to understand what is happening. It oftens feels like he is acting as he repeats himself so often and he does odd things like flushing the toilet a lot of times or showing his money purse constantly. He was such an active person before this happened - he'd never ever stay indoors and now its like watching someone imprisoned as he wanders around the home. My mum is suffering from renal failure so I really look after them both. My dad's "activities" tend to wind my mum up so her blood pressure increases. I feel guilty as I often lose my temper with my dad and feel like hitting him. The stress is getting to me so much and I often feel that it would be great if he dies. Is this normal or is there something wrong with the way I am feeling? Please can someone give me any guidance/advice on this subject.
