Don't give up. We've seen kittens come pack from this. If the kitten isn't eating as much at feedings, try feeding every hour. Make sure the formula and kitten are both warm. You can try a tiny smear of light karo syrup or honey on the lips or gums if she is too tired to eat. We have seen kittens come back from this but it takes work and diligence.
Did you check this kitten for fleas? If you see any pick them off or you can use a flea come and then dip it in a dawn and water solution to kill the fleas. I don't know how long it takes for flea eggs to hatch so you need to keep checking.
