This is really complicated but I'm going to try to explain. My mum is 75.
Mum and I have been very close for years. Going on holiday together, talking on the phone most days for an hour+. Did a lot for her. Best friends. A couple of years ago we fell out catastrophically. The issues were real and very serious. Her choices at the time were quite strange (for example, believing that someone who had confessed in writing was later telling the truth when they changed their story, supporting a convicted criminal over me) but I took her choices - however painful - at face value.
But since then the bad feeling has spiralled. I've tried to find ways forward but mum has been frankly nasty. I live over 300 miles away and travelled near her for a holiday in the hope of seeing her but she refused to see me or her grandaughter. She doesn't seem rational. She's convinced I'm nasty in total contradiction to everything she knows about me. Meanwhile, the family member who was convicted of a crime is firmly in her inner circle. It's so confusing - I feel like I've lost my mum. She's also outright accused me of things that categorically didn't happen. After sharing some nice photos of the kids and swapping friendly messages between us, hours later I suddenly got a series of nasty messages saying I'd 'called her a fake and a fraud'. I responded I never said any such thing. She said 'I kept the messages'. I said 'Ok great - screenshot me the messages and show me right now!' and she said loftily 'I don't need to. I don't tell lies. Just scroll up in your own messages'. Despite knowing I never said anything like that, I did check and of course there was no such message. About a week later she said breezily that maybe it was someone else that sent the messages and that it didn't matter anyway. This hasn't been the only time that she's lied - well I don't know if she's lying or confused. If she'd scrolled up, she'd have seen that the messages she was apparently referring to didn't exist? She then claimed maybe my sister sent them - my sister has been NC with her for over two years so she must know that's untrue. Her texts are occasionally full of grammar and spelling errors - she's usually like a grammar police type.
Mum's health isn't good aside from this. She has very poorly controlled diabetes 2, high blood pressure, a few stone overweight, joint pains. She falls asleep a lot during the day. I suspect she's also had depression for a long time (decades) as her moods have always been very erratic. Extreme lows ('I wish I was dead') and then fine a few days later. No family history of dementia.
One final complication - she's a single foster carer for a troubled (unrelated) 14 year old girl. She was placed as a baby and the situation has continued and now things are really bad between them too. I think social services are aware it's turbulent but I'm fairly sure they consider mum to be healthy enough to care for her. The child thinks of her as mum.
For all the reasons above, I'm worried about her health and the repercussions but I don't know what to do. I'm far away so I can't take her to the GP and have no real handle on her health. I can't go and see her because she hates me. I have no medical power of attorney or anything. If I write to the GP I guess they might call her in but if they say I've written, it'll be the last nail in the coffin of our relationship and I'm not sure what they can tell from an appointment anyway - plus I'll never know what comes of it. My sister is NC and my brother is the one with the criminal conviction and can't be trusted to have her best interests at heart. Do I just have to leave this situation to blow up however it does, since I'm locked out now? If you got this far - thank you for reading. I'm heartbroken. xx
