"I am blessed truly in every way for the treatment received and will for the rest of my lifetime. I have no fear, I know this body of mine is able, willing & wanting to live to my fullest.
"I'll seek my joys from wherever I see, hear, feel them. You are loved, you are held and you can do anything.

"I will take this next stage as I need to, slowly. I'm in no rush.
"I'm filled with joy, grace and love. If truly honest, I am at one with this amazing body of mine and all she has done, given life, survived operations and will now daily fight my cancer.
"She is it all for me and it is time to go home. I have no words for the gratitude of receiving visuals of your joys.
"They truly raised me and I feel the love within them. May you always know joy and continue to share because each of us matter and joys are made to be shared and multiply.
