Oh Val,
So sorry for what's happening in your life, but it sounds like you have the right attitude--crazy as it might sound to some, Gall-bladder removal can't be fun, but yes, you just get to focus on something else for a while--let them look after YOU and get you well, so you can go back to the battle 're-energised'
As no doubt you have read, this battle won't be easy, but take heart from the many survivors here, and get the docs to treat the nausea problems.
I've had little of that, but just a little was enough to make me feel lousy--medication for it was a lifeline!
Keep us posted as to how you are both doing,

Brenda
