Selena Gomez and the rest of the cast of Sebastopol-filmed Netflix series "13 Reasons Why" will forever remember their time working on the show. On Sunday night, Gomez and co-stars Alisha Boe and Tommy Dorfman revealed on Instagram that they got matching semicolon tattoos on their forearms in celebration of the show's completion and positive reception.

As punctuation, a semicolon is used when an author could have chosen to end a sentence, but chose not to. A semicolon tattoo represents the battle with depression, when someone could have chosen to end their life, but chose to live instead. "13 Reasons Why" which debuted to high praise and outstanding reviews, showcases the aftermath of a high school student's suicide.

Before "13 Reasons Why" began filming, Gomez looked for professional help in the wake of her Lupus diagnosis as well as her struggle with depression.

“I think the message, how I felt when I first read the book, I felt like Hannah, and now, seven years later, I still felt like Hannah even more than I ever did. So I think the message and people, no matter what age you are, can relate to the story," said Gomez during its premiere.

In an Instagram post, Dorfman also revealed his reasons why the semicolon tattoo was so meaningful.

"I struggled with addiction and depression issues through high school and early college," he wrote. "I reached out and asked for help. At the time, I thought my life was over, I thought I'd never live past the age of 21. Today I'm grateful to be alive, in this new chapter of life in recovery, standing with my colleagues and friends, making art that helps other people."

Gomez, Boe and Dorfman wrote on Instagram, "Wish the rest of the crew was with us today. Overwhelmed with the response and love @13reasonswhy is receiving. Thank you to each beautiful person who has watched and talked about the message of our show."

The entire first season of "13 Reasons Why" is currently streaming on Netflix, and rumors have circulated about a second season.
