In a recent YouTube video, Acosta read a heartbreaking email from a 12-year-old girl with cancer.
The message read as follows:
Killada, about a year ago I learned to love myself, regardless of what others may think of me. A few months ago I was diagnosed with cancer. I had learned to love myself thanks to your videos, but now I am too skinny and bald. I feel so ugly, I just want to die. Hopefully one day you will answer my message.
Acosta's response to the email shocked fans to the point of tears: The social media star shaved her head in solidarity with the young fan.
Said Acosta, "First of all, you don't need this [hair] to be pretty. What makes us beautiful is how we are on the inside and how much we can love each other. Those things cannot be seen on the outside."
