Buy a digital thermometer and hydromter as the stick on ones are crap. If you have the stick on ones you could be cooking her. Her basking should be 80-83 degrees and the ambient temp should be about 70.
Try making a dripper for her, a plastic cup with a hole poked in it is good. Get it to drip about one or two drops a second. Remove the substrate as she can eat it. If she eats it it can block her intestines (impaction.) an impaction can kill her. She should not be getting so much d3, she needs plain calcium on most of her feeders.
Live plants help bring up the humidity, I recommend pothos, ficus, hibiscus, and umbrella plants that have covered fertilizer free soil. Veileds also eat plants, so make sure they are non toxic. If she eats any fake ones she could suffer from an impaction. Block off her veiw of the fish tank.
Take her to a chameleon experienced vet. She sounds like she has MBD which is not good. She needs vet care.
