You keep her in a room that is that humid and that hot? Humidity and heat in Houston is high all the time, but indoors it is not. Our temps indoors we don't keep above 74, so unless you're incredibly acclimated or keep her in a separate room, I find it hard to imagine living in 80+ degree heat and high humidity.. If you have no way of measuring the temperatures and humidity in her enclosure it may be hard to regulate. But, if you've had her a for a long time and have never had a problem with her sheds, humidity is probably fine. As someone else suggested, I do not think her enclosure is too big. Ball Pythons live in cramped burrows and termite mounds, they just need enough room to regulate their temperature. I'd try putting her pot back in and see how her behaviour changes.
