If she has a respiratory infection she needs to see a certified Reptile vet. Which I'm going to be honest it's hard to find one, and even harder to find a good an reliable one in a lot of states. Our super pastel is battling a R.I. as we speak. He does nothing but hide and hasn't eaten in 2 months. You can't get a vet apportionment like a.s.a.p. and you think she could die from being starved, then force feed her.... but the draw back to that is it is extremely stressful on the snake, and even worse in her poor health it could make her worse. If you do want info on that, you'll have to ask someone else, in five years I've only had to force feed once And all I did was hand the man the food. She sounds absolutely horrible... and IM sorry to hear how bad of health she's in. Regardless of what I, or anyone else says, she needs to see a vet. Good luck.
