About a week ago I ended up taking her to the vet when she regurgitated a bunch of water an mucus. When She was examined and got test results back, it turns out she had an entire stomach and digestive system full of parasites and because of that, had both a blood and respiratory infection. Since then, she's been put on antibiotics and was given something for the parasites. I'm still waiting for her culture test to get back. The antibiotics have helped a lot with her mucus problem, she is no longer gasping for air or gaping her mouth and drooling/bubbling everywhere. She has also got like three layers of shed off her, and two layers of eyecaps which had previously basically blinded her. Overall, she's doing a ton better. The vet said that if I hadn't taken her in when I did she probably wouldn't have lasted but a few more days because she was in such bad shape. Despite the $274 bill, I don't regret rescuing her for even a moment. How anyone could let an animal get this bad then just abandon it is beyond me.
