A 13-year-old British teenager left a heartbreaking message for her family to discover after she passed away from cancer.

Athena Orchard tragically lost her battle to osteosarcoma in May of this year. Now her family have discovered a secret message the teen penned on the back of a mirror in her room. According to People, Athena’s father Dean found the 3,000 word letter at the family's home in Leicester, England. Dean told People: "She never mentioned it, but it's the kind of thing she'd do. She was a very spiritual person, she'd go on about stuff that I could never understand – she was so clever." The family also discovered a box full of original songs and poems. Mother Caroline said the message will help keep Athena’s memory alive. “We're keeping the mirror forever, it is a part of her we can keep in the house, it will always be in her room," she said. "Just reading her words felt like she was still here with us, she had such an incredible spirit” she said. The message in full reads:

“Happiness depends upon ourselves. Maybe it's not about the happy ending, maybe it's about the story. The purpose of life is a life of purpose. The difference between ordinary and extraordinary is that little extra. Happiness is a direction not a destination. Thank you for existing. Be happy, be free, believe, forever young. You know my name, not my story. You have heard what I've done, but not what I've been through. Love is like glass, looks so lovely but it's easy to shatter. Love is rare, life is strange, nothing lasts and people change. Every day is special, so make the most of it, you could get a life ending illness tomorrow so make the most of every day. Life is only bad if you make it bad. If someone loves you, then they wouldn't let you slip away no matter how hard the situation is. Remember that life is full of ups and downs. Never give up on something you can’t go a day without thinking about. I want to be that girl who makes the bad days better and the one that makes you say my life has changed since I met her! Love is not about how much you say I love you – it’s about how much you can prove it’s true. Love is like the wind, you can feel it but you can't see it. I'm waiting to fall in love with someone I can open my heart to. Love is not about who you can see spending your future with, it's about who you can't see spending your life without... Life is a game for everyone but love is the prize. Only I can judge me. Sometimes love hurts. Now I’m fighting myself. Baby I can feel your pain. Dreams are my reality. It hurts but it’s okay, I’m used to it. Don't be quick to judge me, you only see what I choose to show you... you don't know the truth. I just want to have fun and be happy without being judged. This is my life, not yours, don't worry about what I do. People gonna hate you, rate you, break you, but how strong you stand, that’s what makes you… you! There's no need to cry because I know you'll be by my side.”
