Hello Seedee, I am so sorry for what you are going through.  I know how exhausting it is to be a carer when you have health issues of your own.  I was wondering if your brother has been offerd a place in a hospice?  Last year when my brother-in-law was dying of cancer and it reached the stage where he could no longer do anything for himself, he was given the option of carers coming in or going in to a hospice.  He opted for carers to tend to him at home, and I have to say that the standard of care he received was excellent.  There was a carer at his home with him 24/7.  They took it in shifts where there was always someone with him. Do you think that a hospice is something that your brother would consider?  If he is agreeable to the idea, perhaps  you could speak with his Doctor or his carers about it?  Good luck Seedee, xx
