Mother's desperate search for missing teen

*Update 6/18* Glenda Smith tells FOX 7 that her son has been found and is back with his family. No further details were provided.

The original story is as follows:

A West Texas mother is desperate to find her missing son.

It's a situation Glenda Smith never thought she'd find herself in. 

She's been searching for her 15-year-old son Justin Douglass for days.

She and her daughter drove more than 5 hours from Snyder to Austin to find him. 

"Please come home it's time to go home," said Smith. She said the last time she saw Justin was back in May when she dropped him off at a local treatment facility in Austin. 

After being there for weeks Smith received a call from one of the facilities employees telling her that Justin was missing. "They told me Justin had left the facility.  I'm not sure what they said after that because I just went numb I do know I told them I'm on my way," said Smith. 

Since that phone call, Smith and her daughter have been posting missing fliers of Justin around Austin in hopes that she'll get some answers to the where Justin may be or that Justin may see them and come home. "We are walking around talking to people we keep going back to the facility in hopes that he will be looking for us. We cry we cry a lot," said Smith. 

She said it's every mother's worse nightmare and fears the worse.

"The city is so big we're not used to this. Everything is different.  I'm afraid he's going to make a mistake and get hurt. I'm afraid the people he's with could persuade him into doing things that aren't safe. I have so many concerns and my mind jumps from thing to thing," said Smith. 

Justin's sister Cassidy Douglass said she's heartbroken over the matter. 

"I feel real empty I feel like I lost my best friend and I don't know where he is," said Cassidy Douglass. 

Both mother and daughter said they will continue to search for Justin until he's home safe. 

"I love him so much I won't leave till I have him," said Smith. 

Smith said Justin was last seen wearing a bright blue polo and blue jeans.  

He's medium height with brown hair and blue eyes.
