Beata Candre has been missing since October 12.
On Wednesday, police held a news conference along with Candre's parents, making a plea for information.
Candre, a wife and mother, suffers from a medical condition and disappeared on the way to an appointment. Authorities say she was driving a black Jeep Grand Cherokee.
"We love you, the kids love you, we miss you, please come home," said Tony Dzierzak, Candre's father.

"If you can go to the hospital or anybody and try to call us try to call the kids or tell us where you are because we love you and we want you back," said Dzierzak.
Candre, 48, was last seen Friday October 11 and reported missing the next day by her husband. Schaumburg police say the mother of three teenagers has depression issues. She took off for two days in August. But now she's been gone 19
"This is very disconcerting to the family and the police department that we have had no contact," said Sgt. John Nebl, Schaumburg Police Dept.
The police say they had numerous leads to follow up on, including sightings around Chicago and as far away as Nebraska and texas. And as far as Candre's money, bank accounts or credit card usage go, police will only say their investigation has not led them anywhere concrete.
"We are concerned for her mental and physical well-being, and again she has not been heard from since October 11," said Nebl.
The Dzierzaks were part of the post-war wave of Polish immigrants who settled on the city's Northwest Side. Jadwiga Dzierzak echoed her husband's entreaties while saying she had been scheduled to have her daughter over for dinner the day she was reported missing
"We are a really loving family for many, many years since we came to this country," said Jadwiga Dzierzak.
Candre has a 19- and 13-year-old boys and a 17-year-old daughter. Her husband is in contact with the police daily. Schaumburg police want to be very clear; they say she left home "firmly of her own accord."
