My kitty is sick 💔

I just got my kitty, Daphne, a couple days ago and I think she has a cold. She's been sneezing a lot and today she sounds very stuffy. She's 6 months old.  I don't have a lot of money and can't take her to the vet. There's been a couple times where she catches her breath because she is trying to breathe out her nose and can't. 
She is still eating and drinking plenty but I'm scared to death for anything to happen to her. It's just my luck with animals and them getting sick :( I had a puppy named Ruebee and she passed away from parvo. I just don't want anything to happen to her. Any suggestions??? Please help!Â
