I desperately need help

Okay so a little back story. This is my cat daisy she is a three year old tortie. I have taken her to the vet 4 times in the last month and everytime they throw me a $300 bill and nothing has helped. She keeps constantly sneezing and looks uncomfortable. She has discharge in her eyes and has not gotten up at all in 2 days. They gave her some steroids shot and then viralys. I cant afford to keep taking her to the vet to no avail so here I am. I have tons of pictures and videos but im not aloud to attach pictures or videos here so please reach out so I can send the videos.
