Hello Mibster, - you have obviously been through a great deal in the last two years, but it sounds as is you are doing very well
Its only natural to get the odd down day, - we all do. I hope you find the psychologist helpful, - I saw a counsellor and found it a very helpful experience. I've found BCC a useful organization too - I've been to quite a few information sessions they run.
I think the main thing is to grab help wherever you can to help you get through it all 
Pink - lymphoedema - what an absolute pain, you have really been through the mill with that arm haven't you
I hope the appointment goes well and they can do something to help.
Smee - lard arseing around is exactly what you should be doing, get those feet up and relax. Hope the surgeon gets those drains out for you, you'll feel much better when they've gone.
Don't work too hard Cakes - you'll run yourself ragged,
I have made DH's cake, I'm doing afternoon tea for him, - Coffee cake, little sandwiches, and home made scones with jam and cream. On with the elastic waisted trousers I think.
