although - re sleep, and just as a reminder that this is the way things go - I of course have just had two nights in a row of about an hour or two's sleep...But I am working on differentiating between the physical unpleasantness this causes (upset stomach, headache, tiredness, sore muscles etc) and the psychological baggage that my brain wants to dump on top of it (anxiety, worry, self-pity, depression etc). The former I can't do anything about, the latter serves absolutely no purpose. So I just have to stop wasting time with it....
