Ball Python is suddenly aggressive

[Laughing Fish]

Greetings!
young adult female ball python. I have never had any problems with her, as she has always let me hold her, and has always ate quite well. However, when I was rearranging some rocks in her enclosure, she bit my finger and wrapped around my hand, trying to constrict it. She is not very large, so no damage was done. I just waited for her to run out of energy, and gently pulled her off. Since this, however, she has refused to hide in her hideaways, and follows me with her eyes if she sees me. I figured that she just needed some time to rest, so I turned out all the lights and let her have some privacy. This morning, however, when I turned her lights back on she immediately came out of her cave and stared at me. I have never fed her in her enclosure, as I have a box that I feed her in. I do not think she needs to eat again yet, as her last meal (medium frozen rat) was approximately 72 hours before this incident. She is clearly extremely stressed. Does anyone have any suggestions on how I can calm her down?

Thanks in advanced!
