Danielle Locklear, 15, was last seen by a family member on March 11.
Investigators said she left home last Tuesday night saying she was going up the street to a friend's home, but she never made it there.
"I want my baby to come home," said Locklear's mother, Rowna Fowler. "No one knows what a mother goes through. I'm feeling like my heart has been ripped out."
Police don't know if she is alive or dead.
"Every avenue is being investigated. Every lead is being pursued," said Hope Mills Police Chief Joel Acciardo.
Fowler said some of her daughter's clothing was found at a creek-bank hangout that is popular in the area last Thursday.
A task force of agents from multiple agencies is working together to find Locklear. Dozens were out Wednesday searching a campground for clues.
"I am really scared. I want her to be found, but I am also preparing myself that she is not," said Locklear's friend Alexis McDowell.
McDowell said she talked with Locklear a few days before she disappeared, and said Danielle made no mention of leaving home, or running away.
Hope Mills police are asking for the public's help to bring Locklear home.
"Even if you think your information is not important, or you think someone may have already reported it, what you know, please contact us anyhow," said Acciardo.
Meanwhile, a heartbroken mother hopes and prays for a miracle.
"If you please know where my daughter is, any information, please tell her to come home," said Fowler. "Danielle, if you see this, please come home. I love you."
