It's a mother's worst nightmare. Tereza Thomas, 13, has been missing since February 4.

"We have not slept. We have not ate. We have not gone to work," said mother, Tereza Thomas, whose daughter has the same name.

Family members say the teen is a cheerleader, on the honor roll, and plays on a travel softball team. They say it is not like her to simply leave and not come home.

"We're such a close-knit family. We do everything together. And, she's surrounded by loving people," said grandmother Doreen Olsen.

The family has been putting up fliers all over the area in the hopes that someone will spot the missing girl.

Stockton Police say the teen was last seen at her North Stockton home a week ago. They say she is vulnerable, being so young and having never gone missing before. She may be in Modesto or Sacramento with what police say are "unknown friends."

"And she just loves life. She loves her friends. She loves school. And, this is just very out of character for her," said Thomas.

The family has fanned out across different cities hoping for any trace of who they affectionately call "TT."

"Just to picture her and she's listening to her music with her headphones and watching her do her sports. She's just a dynamic. She's dynamic," said Olsen.

Tereza is 5 feet 4 inches tall and weighs 125 pounds. She was last seen wearing a gray sweatshirt, gray pants and white shoes.
