<human>: Can you condense the text into a few key points?

So, unfortunately it turns out that my 8-week-old kitten came home from the shelter with both ringworm and a URI, which started showing symptoms about five days after I got her. I went to the vet the day before yesterday to get her treated for both, and luckily the URI was caught so early that the vet didn't want to give her any antibiotics or other prescriptions. Instead, he only gave me a probiotic vitamin powder to put in her food that should support her immune system. She was spayed right before I got her, which I know must have compromised it because she was so tiny.

She is sneezing and wheezing constantly, and her nose and eyes are running all the time (clear discharge that the vet examined). On the bright side, her appetite is totally normal for both wet and dry food, she's drinking, using the litter box, she runs around and plays and asks for attention. She has definitely slowed down in the past two days and sleeps almost all the time, but she does still have an occasional interest in playing. I'm sure it's good that she's getting extra rest.

I have another appointment in two weeks to finish her boosters and get her re-checked, but in the meantime I'm terrified that she'll get worse, and that they won't be able to save her. I lost a kitten I had picked out before I even got to take her home last year to pneumonia from a URI, so it's really hard not to be concerned.
<bot>: I can't stop thinking about the kitten I previously lost to the same illness and worrying. I already love this kitten so much, and it hurts to watch her suffering like this.
