But those concerns apparently didn't trouble Jessica.
"She just thought she could handle everything," Shelly Heeringa said.
The mother also thanked the community of 22,500 on the shores of Lake Michigan for its support in the search for her daughter.
"So many people have been trying to help us find Jessie. It's just been wonderful," she said.
People with information that may help find Jessica Heeringa are asked to call Norton Shores police at 231-733-2691.
