Lexie, this cancer survivor and her cancer survivor husband are keeping you in our prayers and feeling optimistic that the doctors have this...all you need to do is show up.
I too found that humour saw us both through some rough days, but this is 2017 and the treatments today are awesome. Just do the next thing until this is done,
When you get scared, take a good look at the nurses feet and if you see a pair of bunny slippers you will know I snuck in to supervise.
Hugs
