Los Alamitos, California - Kaylie Castillo, 16, says she's been bullied to her breaking point.

The Los Alamitos High School student told CBS2's Stacey Butler Wednesday she was bullied all last year and the harassment started up again two days ago.

"I just want it to stop," said Kaylie, who's afraid to go to school.

Last year, someone allegedly vandalized her locker and left a mouse in it, wrote obscene things about her in the school bathroom and spray-painted "slut" on her driveway. The culprit also left excrement at her front door and covered her mom's car in baby powder. Then, promiscuous texts were sent to a boy at school as if it were coming from Kaylie's phone.

On Monday, Kaylie said, "it all started happening again."

Someone took a picture of Kaylie's face and placed it onto a pornographic photo of a woman. The photo was put inside all the lockers at her school.

"It made me feel really embarrassed. I didn't even want to go to school the rest of the day because I felt people were looking at me and laughing at me," she said.

The photo ended up on Instagram, Facebook's photo-sharing social network.

"Kids have lost their lives over this. It would break my heart, I'd be devastated," said the girl's mother, Tracie.

Kaylie's parents have filed a police report and asked the school to investigate the alleged harassment. Nevertheless, they say officials have not done enough to stop the bullying.

"Now, they're taking it further, and further, and further," said Kaylie's father, Guy. "It's getting worse, and now, all of a sudden, we are getting into pics and pornography. The school needs to step up and do more, they really do."

The girl's parents want the harassment to stop and are offering a $1,000 reward for information that leads to the person responsible.

"Whoever's doing this to my daughter should stop, just stop. Enough is enough," Tracie Castillo said.
