MIL in hospital

My MIL has been diagnosed with demetia. Shes in complete denial, refusing help and accusing everyone of trying to 'drive her twisty'.
My sister in law is over from the US and is staying with Mum. Mum has been being sick a lot last week, and yesterday she complained of chest pain and ended up in hospital.
Shes still there, having alsorts of tests.
Its her birthday today.... not quite the way she hoped to spend it. 😒
