@notapizzaeater: I'm so sorry to hear about the uncertainty with the results and the need to wait for more. The endless waiting and uncertainty was almost the worst bit for me.
Thanks for the support, guys. Things feel - and are - very strange at the moment. i keep hearing from the hospice that things have been difficult, but he actually sounds calmer there than he has been at home. They want to get a legal agreement that they can treat him against his will, which I have agreed to, though I don't think he will object. They are thinking that they probably do need to sedate him for a bit, though not enough to knock him out. They have said that I can be there longer than the 3 hour afternoon visiting slot if I want to and if it calms him. I can't say I'm leaping at the opportunity, as the rest feels very necessary. I'm not sure my presence makes much difference to him but I'll see how he is when I go in this afternoon.
I requested brochures from some local nursing homes to begin the research on what is available and I have been inundated with selling phone calls from a number of them, wanting all the details of what care he needs, which I really don't know yet. It has rather put me off a number which looked promising.
Basically, everything is very up in the air and I feel very lost. DS is being very withdrawn and not really communicating at all. It is all really lonely.
