Any recourse for under the table employee and breach of contract, unpaid wages?

I have voice mails and text messages from my boss attesting to my great performance at work. I was paid off the books, and under the table by her for over six months. I have evidence as to the contract, work schedule, pay, and duties required.
After my boss attempted for months to get me to date her son, and my continued refusal to date him or watch her granddaughter (son is a single parent, boss performed many motherly duties while trying to manage her accounting and tax preparation business) I was let go without agreed upon pay, prior to the realization I was in a relationship and had no intention of dating her son, my hours were reduced from original contract. When I was terminated, she texted a litany of comments to substantiate my mistreatment and breach of contract. Since I was not on the books, supposed to be an independent contractor, employment spanning 2016 for approx six months. Do I have grounds to sue for back wages? Breach of contract with reduced wages? Harassment? etc?
