Hi MimoMilo
I feel for you.
After 10 weeks you hope that things will have settled - however the only constant is that nothing is predictable
I hope that having had her say, your mum will have a calmer evening - the staff will be with her and watching out
and I hope you are not too shaken, and not remotely considering ..... no need to write it as I'm sure you're not
maybe set up some warning system with the staff so that you can have a response prepared and just parrot it out - even better (?) can you ask that your mum doesn't make such calls eg their phone may be out of order or they know you are out at the cinema (and may leave a message for you, if she keeps insisting)
I found with dad that over time the staff learned ways to cope with him and support him, so they take the brunt of these situations, for which I am grateful
glad you posted to get it off your chest - now breath, relax and have a cuppa or your favourite tipple
