none of this is easy, even when its a good day its in the back of your mind that it wont last, I think its a brill idea to record the good times, so you can read them later, I wish i had done that with mum,
you say he looked grey and at one stage flushed, I think its an infection, mum always went white as a sheet often the doc couldnt find anything wrong and sample of wee ok like your doc ours prescribed antibiotics n mum got better. so i do hope its the same for you,rather than he is getting worse.
sending you a well deserved ((((((HUG))))))
