"I’m so thankful to my friends and family for loving me through this. I’m so thankful to John for the nights he spent researching what every operation and medication meant and what side effects and recovery I could expect. For being there before I went into each surgery and being there when I woke up, always placing framed photos of our little boy Malcolm so it would be the first thing I saw when I opened my eyes."

"Thank you for fighting so hard to be here for us. Malc and I adore you."
