Caring for mother with Parkinson’s

Oh dear what have we done?? 3 years ago my mother came to live with my partner & I, we built an wet room& bedroom extension for her, so she now has her own sitting room, bedroom & wet room all on one level, but sadly the time has come we need our life back, she listens in on our phone conversations & never has a conversation with us as her head is Always buried in her iPad on Facebook looking for latest move of someone/ anyone. Sadly she has started to lie to us, thinking she knows best on parky meds!! not taking meds, removing tablets from blister pack & hiding, hiding food for eating later when she goes to bed!!! And more. But I need advice to help us with the next suitable move for mum with Parkinson’s.
