I'm sorry for making you feel bad, that certainly wasn't my intent. You wanted to know what caused it, so I was answering your question based on the info you provided. I'm not saying 'you killed her', I'm saying it sounds like you were misinformed on what she needed. Unfortunately that is common with exotic pets, and they do suffer from it because they are fragile. But with research now knowing which things can be changed you can be successful in the future.
