Welcome, Elin
((HUGS)) to you and a warm welcome. I wish we had met somewhere other than here, but hey -

We will make the best of it all, right?
Feel free to ask anything at any time - you are amongst friends and not only friends,, but people who have been where you and your husband are right now ... so feel free to express anything and ask what you wish to know .. we are here for you.
I wish your husband Godspeed for his treatment and recovery. May his trials be few and his recovery be complete.
Again, welcome! It is nice to meet you.
