I think the major reason she's cranky is husbandry. Temperatures really shouldn't be a guessing game, no matter how much worse her situation was before. I feel your pain that everything feels so expensive, especially starting out, but believe me when I say that the piece of mind it gives is worth whatever the price tag is.

Are you measuring humidity at all? Jungle mix and multiple daily mistings might leave you with really high humidity.

Lastly, I highly recommend feeding her in her enclosure. A BP will not mistake your hand for food, as long as it doesn't smell like her food. She already sounds stressed, so moving her around before and after feeding probably isn't helping her to relax.

And where are the pictures, no thread is complete without pics!
