Hi. I rented my home out to my granddaughter and her friend. They were to stay until Aug 31. But I now have nowhere to live. Can I return home

Moved to NC to be with a friend. It didn't work out. I'm now living out of my car going from place to place. I have a four br house and I wish to return to my home. The girl, and my granddaughter are saying it's not fair. The girls mom is threatening to take legal action. I have offered to lower her rent, I have offered her a free months rent and return her security, she declined. I thought I had worked something out with a friend but it didn't work out. So again I offered to lower her rent and again her mom is threatening legal action.
