In an interview with People, Robertson got frank about what really happened that led her to believe she needed to get checked out.
"This one was not just me," Robertson prefaced in her defense. "I found this dark blue slash black thing like this big on my foot," Robertson makes a circle with her fingers that's about the size of a quarter, "and I'm like, 'What's this?' And it was there for, like, two weeks so I'm like, 'Oh my gosh, I think I have cancer,' because obviously that's where I go to."
Robertson took her concern to two of her family doctor friends on separate occasions, who both said that she needed to get the spot removed immediately because it looked extremely serious to them.
It wasn't until the young star went to her dermatologist that things turned from scary to hilarious. She said the doctor took a closer look, scraped at the spot, only to discover that the bluish black mark wasn't in fact cancer but a smudge from a Sharpie pen.
On a more serious note, Robertson touched on the not-so-glamorous aspects of being in the public eye.
"I actually just started journaling," Robertson revealed about how she stays on track, "because life is crazy and life goes by fast and you forget things."
She explained that writing things down helps her to track her progress in life and get through bad days.
She hopes the book will help young adults in a similar way by helping them just to be themselves. "I think there's so much pressure to be this certain thing and this certain goal in the world, but it's OK to be yourself. And so this book is kind of just giving people a voice."
