Sorry, Dragon, I went back a little further and found that you worked together. I know its hard - believe me - and hindsight is 20/20, but even leaving the card on her chair would have been better.

When you hand it, and break down, you force her to put up her walls of guilt/shame/anger, etc. Obviously, it's too tough for you to control your emotions, so keeping yourself out of the situation is better. Hey, take a deep breath, step back - think it through more carefully next time.
