Obviously your family is very close and you discuss the situation every day, but now things are changing ('2 lines crossed') maybe it's time to have an Official Family Conference?
You could discuss plans for the future (i.e. moving mum to a care home, as you accept it is inevitable sooner or later) and get input from everyone on the time scale as they all see it. Next step is to plan how you will achieve it - easier said than done! The third step is to discuss how you will all cope as a family until that time comes and how you can support each other now your mum is becoming... difficult.
I just think that if you had a definite 'goal' you were all working towards, it might help your daughters and husband cope. Sometimes the worst thing about coping with caring is that there is no 'end date'. Thinking it could go on forever (getting worse every day) can make you feel desperate but if you can say 'it's only till spring' or whatever, it might be a little easier.
