Sweet very ill TNR kitty needs help!

I was greeted at the door from the lovely manager from Mas Tacos with this girlie because she thought it was my naughty kitten cricket who went missing and returned same day a couple weekends ago! I forgot to tell staff at Mas Tacos that the hellion was back and I was greeted with this feral sick angel baby at the door. I couldn’t turn her away, in fact I’ve been calling her Blondie already. I cannot keep her! Adding in the cost of her treatment and the cost of another animal is not an option! I was an active foster in Seattle but just relocated to Nashville and don’t know where to turn because she’s clearly TNR but she’s bad off. Does anyone know of any rescues or no kill shelters that would pay for medical treatment? I’d be happy to foster until shes ready to go to a home but I have a very young cricket, an older cat and an elderly dog so budgets are strict! I’ve already reached out to The Catio, MACC, Pet Community Center and Nashville Cat Rescue. She is extremely sick and I am scared to expose my very young kitten and older cat Loki.
