Help please I need help

I’ve been lying about who the father of my daughter is to my family. Her bio dad was physically abusive towards me and threaded to hurt us so shortly after finding out I was pregnant I ran. My guy Bestfriend offered to tell my family that he’s the father so that her real father could remain anonymous. So as far as my family knew my Bestfriend was her dad. I need to file for emergency food stamps earlier this year after losing my job and they made me open a child support case In order to get assistance so to buy a little time I just opened the case with my Bestfriend listed as the father.. Until today a paternity test fell out of my purse and my aunt read it. Now I need another lie as to why it’s saying he’s not the father. I was thinking about just telling her that he did a home test with a different child and took the results to the child support office. I really can’t have my family finding out about my crazy ex. They’ll tell everyone and soon he will find me.
