missy, im sorry you are having a tough time. Just remember that in a few weeks, it will all come second nature to you. I know that does not help you right now, but the point is that learning this job will come to you, it normally takes a person 2 weeks to learn a new job, plus you have not been given that much time to learn your job. Just hang in there sweetie, i know its hard. I have changed jobs a few times, and it is always overwhelming.
Dont be afraid to speak up and make sure that the other girl knows that she does not intimidate you, even if you are not intimidated, she might be trying to.
I dont know if i made sense, but all in all, i know you will be good at this job, you have such a sweet personality that shines through on this board.
