Thank you all so much for your kind words and advice so far. It's so comforting to know that there are other people out there who have been through the same thing, and that makes me feel so much stronger.
Apparently my wife (Donna) has had lots of rest last night, which it great news, and they're letting me come down a bit earlier today in case she wakes up in the morning. As you say, it's a matter of taking each day as it comes and being thankful for each tiny step along the way. Of course you're right that each day she does get a little better - yesterday she managed to eat for the first time all week, and I can't tell you all how proud I was of her for that.
One question for you all - the news spread very quickly that Donna was very ill, and there have been dozens of people asking after her. It seems that everyone wants to come and see her. She's had some visitors already - her mum, and a couple of her closest friends, but the visits really do tire her out, and I've found that people are needing quite a strong nudge when it's time to leave. Today her dad and sister have shown up unexpectedly and want to pay her a surprise visit, which is frustrating because I was hoping to have a quiet day alone with her and not have to worry about looking after both her and her visitors for a change. Perhaps that's a little unreasonable of me, and perhaps I'm feeling too much that it's my responsibility to bear, but that's how I feel.
Anyway, how did you handle visitors during the early stages? She is lucid enough to hold a conversation and says she wants to see people, but I get the feeling that she wouldn't really care whether people came or not at this point. Did you appreciate the visits at the time, or was it just something that happened? Or would you rather have just been left alone to rest up? I've put together a scrapbook with all the messages (emails, facebook messages, etc) and cards people have left for her, which she enjoys looking through for a few minutes if she's awake in the night, but I kind of get the impression that the visits themselves are more beneficial for the visitor than her..
