HELP?!- Breathing hard, Scales Wrinkly

I fed her two days ago- haven't touched her.
She's on the cooler, more humid side of the tank, breathing heavily, and if I come near the tank she coils up and acts scared, which is not like her.
Her scales are dull- but her eyes aren't blue- I don't know if she's going to shed or what's up.
She is out of her hide- just coiled up in the corner.
I have no idea what to do.

Breathing heavily sounds like it might be a sign of a respiratory infection. Is she popping, wheezing, etc? Is she breathing with her mouth open? The best thing to do is take her to the vet ASAP if you really aren't sure.

No- she's just breathing hard- her sides are heaving, but her mouth is closed.

What's the husbandry like? Temps? Humidity? Substrate?

She might also be dehydrated considering she ate a couple days ago. Have you seen her drinking?

80 on the cooler side, 90-95 on the other, humidity is 80.
It's a type of bark for the bedding, I know that it's negligent for me to forget, but it's not dusty or bad smelling, it came with the snake, basically.
Yesterday the humidity was 60 so I put some water under the lamp to bump up the humidity because her scales were ridiculously wrinkled and I thought she was either shedding or dehydrated.

I have not seen her drink, but she's been by her water.

50-60% humidity is perfect actually. Most would agree on here that 80% is actually too high. What are you using to measure temps and how are you doing it?

Temperature and humidity gauges on both sides of the tank. I heard 60 was too low, that 80 was the perfect humidity.

Are they the analog type gauges or digital? Are you using a probe to measure belly heat? Also, do you have a thermostat regulating the temp?
