In 2017, Hyland got a tattoo by Dr. Woo of a single thin line going through two overlapping circles of different sizes. On Instagram, she said that the design is meant to symbolize one of her favourite quotes: "the best way out is always through," by Robert Frost.
Hyland got this tattoo during a time period when she's shared she was struggling with depression near the end of nine months of kidney dialysis. Hyland has kidney dysplasia and had her father's kidney for five years before her body rejected it in 2016. She was on dialysis for nine months waiting for a second transplant.
