She is in moderate stage, but pretty "with it." Every time I walk in the door it is not hello it's do this or you need to do that in a very mean voice. My dad also has dementia and I am the care giver. I live with them. I am about to throw my hands up and just leave them on their own. I am the POA and have no help. They don't have enough money to hire help, but make too much to receive benefits. Any suggestions is great.
