HI. I am struggling to do what's best for my mum because of interference from a sister. My mum has alzheimers and is always confused, she cant pay her Bill's or do her own food. I've been doing it 4 years. My mum gave me poa last year. Since then she has gone down hill. Even more so the last two months. She got given pills and they sent her into a jibbering wreck. My sister has realised and is now demanding Poa and was getting my mum to give her credit cards. I put a stop to the cards as I've always dealt with mums banking. Anyway. Mum is loving my sisters attention rightfully so. But in 4 years my sister has ignored me and my mum 4 times. From 3 months to the last which was 6 months. Also at a time my mum got diagnosed with an arrhythmia. Mum cant remember a thing unless she is drunk. And so. My sister takes her out and gets her drunk. Then puts ideas in mums head like kicking me out. I live in care for mum. Which mum does. But then next day she remembers none of it. My point is I want a capacity test to protect mum. To get my Poa in order and carry on as I have for 4 years. Since dad died. I'm fearful my sister has other plans as she is just turning up as if she has run things. Taking bank cards was the last straw. So. I cant get a gp to do a test as its 3 weeks just to talk on the phone. And I need to get mum assesed as soon as possible. Is this wrong of me though I'm unsure. To rush and to get an outsider to decide. I promised her she wouldnt go to a nursing home so I just want to ensure her income keeps her where she is.
