The fact that you have U.S. citizen children does create a path to lawful permanent residence unless one of your children is at least 21 years of age. There are a variety of nonimmigrant and immigrant works visas. Most work visas require an employer to sponsor you. The type of visa you should pursue will depend upon your education, experience, skills, and ultimate immigration goals. Some visas are limited to annual caps so they may not be available until fiscal year 2018. You do not necessarily need to leave the United States; you may be able to change your status if you entered on a visa rather than through the visa waiver program. I encourage you to consult an attorney.
