I agree with what Tuppnce says, you do need to see the Palliative Care Consultant. To see what help he can be given. Not sure if it is still the same as when I nursed palliative patients but priority was given to patients, such as your dh, so that they could be at their place of choice (whether that is hospital, hospice or home). As he says he wishes to go home this should be prioritised and there should be a care agency, with both qualified nurses and health care assistants, who can take on care for patients at home at very short notice. The district nursing service can also provide support and help, should it be needed.
I reiterate what has been said before, please look after yourself, as I know it can be very easy to put all your energy into caring for a loved one and forget to look after yourself.
For you, prayers and ? xx
