Oh wow Willow that's so ace re the lung mets. You're certainly not a fraud, and without you how could we all have 'met'? 
After a very fraught morning helping him get up, then meeting a friend, I came home at lunchtime to hear DH on phone, 'So not today then' and with visible relief he passed phone over. On my being told that the Palliative MacMillan nurse couldn't come today, I had a minor maybe major screaming fit and ranted on about it all being impossible, frightening, no help etc etc.

The hysterics paid off as their Team Leader phoned half an hour later to say she was on her way. She spent nearly 2 hours with us, has prescribed liquid morphine, only as required, to trial. Told DH lots of strings to her bow to defeat the pain and generally cheered him up.
and told me I was absolutely right to have been so angry (I apologised profusely and asked her to pass this on to poor receptionist). 
I'm to monitor his reactions and then, if all OK, DH to be on the sustained release morphine. Probable change of steroids too.
I'm shattered after all the histrionics, so eating chocolate and any other tasty rubbish I can find!
