"Toddlers and Tiaras" star Kailia Posey left behind a note and a gift for her mother before she died by suicide.

Posey's mother Marcy Gatterman opened up about the 16-year-old's final days in a recent interview with E! News.

"The days and weeks leading up to this, it seemed fine to me," Gatterman told the outlet. "I didn't go through her phone. For prom, she went with a bunch of friends. And the next day, everything was fine."

However, on May 1, Posey took a family car after her mother left to go to the store and never returned.

"Dear Mom, even when I'm not close by, I want you to know I love and appreciate you. Always. Wrap yourself up in this and consider it a big hug. I love you," a note with the blanket said, according to Posey's mom.

Gatterman also emphasized parents should be checking in on their children, and encouraged children to open up to their parents.

"Parents who have teenagers, check their phones," she said. "And if you're struggling, talk to your parents. They're not judging you. They're going to get you the help that you need, but we need to know what you need in order get the help you need."
