If you spoke the truth with no intent to upset her, she's the one with a problem. We can't read minds or always say the "right" thing the other person wants to hear. Know your own heart and it won't hurt so bad when someone else has a problem; you'll be free to try and help but if the other person isn't able to use your help then that doesn't diminish you and your good efforts. The only time you should feel bad or upset is when you do something anyway that your heart told you :-) not to.
