Hey Emma.. I tried listening/watching your vid above, but had to stop after 15mins. Based on what I saw, I can relate to many of the things she said.
When I was first diagnosed with lymphoma (same as her) I bawled from my soul to everyone for a day, then I spoke to everyone personally and told them that, no matter what happened, I would not change and therefore did not expect them to change towards me... and under no circumstances would I lose my sense of humour.
I went through chemo (6 months), radiation, and a bone marrow transplant. I'm wearing a wig in our wedding photos.. and I got everyone to wear my wig for photos too. Hilarious shit!
For the best/worst part of a year I was unable to walk, eat (tube-fed), breathe (oxygen mask), and heck, even produce my own blood (blood/platelet transfusions).
During my hotel vacations (aka hospitalisation periods) I can vividly recall my nearest and dearest coming into my room, all scrubbed, gowned, gloved and masked,..talking to me, touching me, even praying for me.. and many a time I couldn't acknowledge their presence because I couldn't open my eyelids, let alone talk.
I remember them tip-toeing out of my room, and me screaming inside my head for them to come back because I was so bored.
I had daily prayer visits from the minister who married me and hubbster.
When I was able to sit up and talk, my husband made a video of me talking on-screen for our baby son because for a while I wasn't able to see him due to him having a cold, my white count level being zero at the time.
For me, I can only put my experiences down to the effect of the incredible drugs my body had to endure.
Anyhoo... that's how I feel about my personal story.
I know absolutely nothing about this lady and the book, but it's clear she has made a positive impact on you and others, and that can only be a good thing.
