Struggling with angry outbursts from elderly MIL who is housebound now. We take really good care of her and she also has carers coming in. We've practically put our own lives on hold to drop everything to care for her. But she regularly attacks us - mainly directed at her son - saying you don't care etc, but said in a really angry way, very nasty and spiteful, face flushed, almost shaking with anger etc. Then the next day, she'll say thanks for coming, nice to see you. It's not exactly new for her to be angry - for as long as I've known her, she's always been very difficult at times and had outbursts about hating different aspects of her life but it is now much more directed at us, although I'm sure that she's fully aware of what she's doing and I think it somehow makes her feel better to hurt us. No dementia diagnosed - potentially could be early stages but I don't think it is this, or certainly not the main cause just angry because she's old and also because she genuinely doesn't like us (or anybody really!). Long history of being manipulative and frankly not very nice or ever supportive to us in any way. So we're really sat here now thinking what the hell - we do everything for you when we're certainly under no obligation, and yet this is how we get treated.
Phew - moan over! Now the thing is - what is the best response? To ignore? Walk off? Challenge it? If so, how? Dh struggling to deal with it so will probably be me who will have to provide any response. Currently I just say no that's not true, she carries on ranting then after an awkward few mins we make our excuses and go (it always happens when we've already chatted, done any jobs and things are 'winding up' anyway).
Any advice please?
