Hi. Thank you everyone for posts - daft thing to say I know when it is people's sad and stressful stories. I don't know where we are going now, but it's going to be in the same direction and I know even now I am having difficulty coping.
Mum (DH's mum) is still pretty independent, but she's lost a lot of capabilities and I can see it growing slowly but steadily.
I've noticed her having mood swings during the day (we live quite a long way away. She calls often several times a day. I field the calls as DH does difficult work that needs a lot of concentration. I've taken to leaving the phone off the hook when I am out, so that people he's working with can Skype him and mum can't call for an hour or two.)
Now recently she's taken to telling us we've cancelled visits, that we come on regular days, and that we are disrupting the "other people" in her life by changing things (which we hardly ever do). There's no argument. We see her once a month, on weekends that both of us can manage, and are more or less on call if something goes wrong, even though we are an hour and a half away. She's done "cancelled visits" a couple of times before, but it's been for a reason (badly written diary, or we really have changed something for a reason) but now it's like a blanket accusation. I'm not handling it well. I've never dealt well with being told that I am lying or making things up, and though I know it's mainly her loss of memory speaking, I don't know how to deal with it. At the moment I am just arguing, because I don't know what else to do or how to end the conversation!
Also, she likes quarrelling, she's even admitted it and this makes my skin creep even if I try not to react. My wise late FIL apparently told her early in the marriage that he wasn't going to rise to a quarrel, because "things get said". He had a much stronger nerve than I do. I just feel backed up against the wall and don't know what to do.
DH handles her differently but doesn't react any better. They just bicker. She has always been a strong personality ( ... ) and she is a strong personality at him - she's more spiteful to him than she is to me, becasue she knows I answer back ... this sadly is her dark side, not the illness. She's not like that all the time, but it's a constant undercurrent.
Venting a bit ... I don't know if it makes me feel better but at least it puts it into words. We don't know how it will go, but it is scary. She is in very good physical health, despite being over 90, apart from glaucoma, which so far she has controlled. My friend's mother was accusing him of hitting her before her life ended, and they had a really good relationship when she was well. Despite her combative personality, I cannot imagine my MIL doing that (she's verbal ...) but I am coming to realise that nobody is immune from anything with this disease. We will have to start handling her financial affairs at some point, too. At present she's glad to discuss things with me, and now I realise this too may change.
At present all I am doing is fielding her calls and visiting as regularly as we can while having a life. It's rung one, and I am already not coping well :-( Has anyone got any suggestions? I noticed some people have been getting counselling. That never occurred to me. I have had some workshop help for anxiety (not just about this, but it's a main cause. The rest is just my personality, I think.). I don't know how to find a suitable counsellor, but I guess I could start by asking my GP?
Will stop now before I use up all the letters in the computer :-)
