Hi
@Bracks48, you sound tired and fed up. I find the mental stress of constantly thinking of my relatives needs is very difficult. You don't need the hassle from your brothers - block them from your phone if they cannot be constructive.
If your LPA's are not registered please do it straight away. I cope by having regular carers for my parents and MIL. It is an extra pair of eyes and then I can worry less about the routine things such as medication and hygiene. Please don't feel guilty about getting in help, make some time for yourself and your grandchildren.
My MIL complained a lot and was rude to the carers, even pushing them out of her house at one stage, but the Admiral Nurse advised us to persist as it would become her "New Normal", which it did.
