MCFARLAND (WKOW) -- Friday marks two weeks since a McFarland teenager disappeared in Milwaukee.
On February 14, police said Sean Baek did LSD with a friend at a UW-Milwaukee residence hall and ran out of the dorm.
Officers said they are still looking but have not found any leads regarding the whereabouts of the 18-year-old.
For Baek's parents, Kristin Erickson and Michael Baek, not knowing has been the hardest part.
"We wake up every morning and think how can this possibly be real," Erickson said.
The couple said Baek is the oldest of their two sons so it was difficult for them to even see him go away to college.
"I had a harder time, but oh gosh he loves college," Erickson said.
They said their son made fast friends at UW-Milwaukee and when he came home after his first semester, they were so proud to see him mature.
"Now it's been two weeks since we've heard from him and almost a month since we've seen him so it's heartbreaking," Michael Baek said.
The last anyone heard from the teen was that Friday morning. He sent a text message to his father reading, "I love you guys. I am so sorry."
"I saw the text message right away," Michael said. "I texted him back and it sounded like he was upset about something so I tried to text and call right away so to have him right there and respond to our messages was really disturbing."
In the two weeks since, the parents have prayed for any news.
"We're hoping he's safe somewhere and we just want him to come home," Michael said.
For now Erickson said they're holding onto whatever hope they can and they're asking everyone to keep their son's picture in their mind.
"We still have hope and we still pray for anybody for anybody who knows anything about where Seanie is," she said. "He has his whole life ahead of him, so come on home baby."
Baek has Type I diabetes and left without his insulin, so his parents said he may have gone to a hospital or clinic. Otherwise, he is in desperate need of medical attention.
"A kid being gone is scary but a type I diabetic kid is terrifying," Michael said.
At the family's request, UW-Milwaukee sent out his missing notice one more time, asking students and locals to continue looking and come forward if they have any new information.
