What do I do? 😱

So I'm 99.9% sure I have a UTI. My symptoms started Thursday. Only problem is I have no insurance and I lost my job last month so I can't even afford to go to a walk-in clinic. I checked the local health department and they don't offer any treatment. I've asked everyone I'm comfortable asking for money but everyone I know is struggling as it is. I'm really worried because I read that if they go untreated it can lead to kidney infections, infertility and probably worse. Does anyone know ANYWHERE I could go?? By the way I live near Knoxville Tennessee. Feedback would be appreciated 😞😣
