( CNN ) -- If I can help one person battling this disease , who 's fighting for his or her life , stay positive by being stronger , then my goal has been accomplished . Finding inner strength at a time when being strong seems like such an impossibility is what can pull you through cancer . The kids at Seattle Children 's Hospital got me out of bed on days that I would n't want to . Kids are resilient . They 'd knock on my door and force me out of bed . Force me to walk -- with tubes in their noses , barf buckets resting on tricycle handlebars , beads of courage clinking from their IV poles . THAT was awesome . Every day was a lesson . It 's a lesson no one is prepared for , and ironically , you have no time to prepare . You are thrown into this , this nightmare , and within hours , your life , your plans , your goals , your future has completely changed . My proudest moment was during a scary clinic visit when I toyed with going into septic shock . My fever spiked , and my blood pressure plummeted -- never a good combination with no immune system . I was minutes away from ICU , and I do n't know what happened , but I rallied and fought , and my numbers turned around . The most awesome moment was walking out of the hospital for the last time . Done . Never looking back . People need to know what goes on behind the walls on the oncology floor . It 's the scariest , most wonderful place you could ever observe . A monumental will to live . A child 's naivete . A parent 's reality , holding onto a tiny thread of hope . These kids exude strength , and it was their courageous fight that made ME stronger . That I will never forget .
