You NEED to let that snake calm down. She's soooo stressed, that poor baby
Stop touching her, stop opening her tank, don't even LOOK at her for a week. Cover her up and ignore her, no peeking whatsoever. Getting her to eat is 100% more important than getting her used to being handled. The poor thing is stressing so much that she's refusing to eat. Once you've let her gone without looking/touching/poking/prying for a week or so, wait til it's night time and offer a warm rodent (whatever she was eating previously, ask the breeder) and put it quietly in her tank. After that, leave her alone. No touching/peeking until the morning.
