So sorry to hear your news, Fanny - you're such a cheerful and positive poster that this must have come as a hell of a shock to you. However, distraction is definitely what you need so that you don't worry yourself into a heap before getting definite news and/or a proper diagnosis. Whilst the hospital is "flummoxed", do try hard not to fear the worst.
Lots of good advice here and warm wishes for you. Do hope that has lifted your mood a little and you're getting some proper rest. For me, being outside is my salvation if I'm very stressed or worried. Just being....on a seat, in the garden, fresh air, all of nature's distractions. I also like to go back in years to something comforting and non-taxing - an old t.v. series, a play, a concert, something I have maybe seen a long time ago and enjoyed, or something new which I can watch and be absorbed in. I'm another Alan Bennett fan and I love foreign travel with maybe Rick Stein, Michael Palin.....or Billy Connolly's old series. Calming 'wallpaper' stuff with lovely views and no stress. Wishing your DH an early recovery and please keep posting, so we don't worry about you ! ??
