Breathing problems

I need help. I bought a ragdoll kitten from a breeder when she was 8 weeks old. About a week after I got her I noticed that she was a bit raspy. The next week it wasn't any better so I took her to the vet. She got some shots for allergies and zithromax. After her zithromax was done she was no better, maybe even worse. So we went back. She got more shots for allergies and put on clavamox. I noticed worms that day also so she was given panacur for 3 days. She still isn't better. At this point, I'm at a loss. She is hyper and playful. She eats and uses the litter box properly. She's never had any eye or nasal discharge. Yet she struggles to breathe it seems. Her third eyelid on the left is usually halfway up. She's not had a fever. She acts 100 percent kitten. Other than these issues. I live in a small town and don't have a feline specialist. Both of her parents are feiv negative.

Also she gained about a pound in between vet visits (10 days) so she is growing

She's precious!  As long as she's eating, playing, and using the box normally, I'd wait a week or so to see if she gets better.  Sometimes it takes those infections time to completely clear up.  The third eyelid up is a big clue that she's not quite 100%, but she may be over the worst of whatever she had and now just needs for the rest of it to work it's way out of her system and let her system fight it off.  You might ask the vet for eye/nose drops like Gentamicin to help clear up the eye issue.  Those can also be used in the nose to help if she's got a stuffy nose.  I wouldn't get her any more kitten shots or spayed (if she's not already spayed) until after this clears up. 

We waited on all the shots she was due for until we knew what was wrong with her. The shots she got at the vet were dexphos and enrofloxacin. She finished the clavamox last Friday. . She doesn't have worms that I can see anymore or fleas.... when I got her she was infested with fleas.
