You go girl!
Has she asked you to write her tests for her yet? Just Kidding.
You seem so nice, but not everyone is, and believe you me , even the savviest of people can be fooled. There are also nice people out there too so don't let this incident make you all jaded and bitter like moi lol.
I wish i could be of more help, but I don't really know the situation that well obviously, but you can be a nice person and still say no, it doesn't mean you wouldn't like to help or are mean, saying no is your right.
So don't fret about it, and the next time something like this comes up you will know exactly how to deal since you are practcing right now:))))
