Some would be damaged, some would take their own lives.
"Young people need someone to listen to them about their problems," she said.
"Teenagers don't know how to deal with stuff, and if no one listens to them they feel they have nowhere to turn. It might not be a big deal to adults, but it is to kids."
There were other issues - there was nothing for youth "up here", nowhere to simply hang out, no one to mentor young people.
"It's having a ripple effect. Every time a young person takes their life it increases the chances that another person will do the same," Caitlin said.
Lights for Life was about showing that there was hope, that others in the community were there for those who needed support.
"I'm proud of the people who came out this morning," she added.
"They are people who care. They know that we need more opportunities for kids to get the support they need. They know it's hard for kids to reach out."
Caitlin also saw a serious lack of mental health services. Kaitaia Hospital had no resources, nowhere for those in need to recover. Those who were admitted to the hospital's sub-acute unit tended to feel they were being branded as crazy, which they were not.
They were then "thrown back" into the environment in which they had been struggling.
Schools were not addressing the issue either.
"It's the elephant in the room. We need to stop ignoring it," she said.
"We just need somewhere where kids can meet, where support groups can make themselves known and available.
"Enough people know about this to do something, and hopefully now that will start to happen."
