awww I'm so sorry. *hug*
I know it's hard, but you need to try to not be too upset or stressed out. at least, not in front of her. Because if you do, then she'll sense it, and she's going to freak. If you are calm around her, then she should be OK. Just give her lots of lovin.
and she'll be so happy to see you when you get back!
Have a great trip and try not to worry.
