What do you do when people are lying about you and there is nothing you can do to prove it and it doesn't matter even if you did?

I recently took a neighbor to the hospital due to excessive puking, seizures, and drug use. I had my mother watch her kids while I to the neighbor to the hospital. It was a rough trip for me, trauma related because I watched my husband die because he wouldn't stop doing drugs. She BM'd everywhere and the doctors or nurses wouldn't touch her. I am a life long server of the lord and I cleaned her up, and kept changing her clothes, holding her hair, and her hand. She had me call all her kids and every single one of them refused to go to her as they were partaking elsewhere. My neighbor is now threatening to get me and my family kicked out because my mother kindly asked her to stop recording us on her back porch, as she told me she was. I feel defeated. Why would God allow me to help some like that, have her lie about what I helped her with? God allowed me to literally continuously wipe her butt while she was pooping on me, for her to say I never even took her into the hospital. Does God really think I'm that trashy and unworthy of a human to be taken advantage of like that? Now I'm going to lose my housing as a single mom with a 1.5yr old Angel because I kindly asked my neighbor to stop recording me and the family.
