She was shocked and obviously had no idea, but was very loving and supportive. She also said she felt honored that I trusted her with this. I had prepped her by warning that I had something really important to share that she had to keep to her self. After I told her, she said something like:

Her: Thank goodness it wasn't something serious.
Me: This is serious.
Her: Yes, but you are OK, and your family is OK. I'm shocked, but I was afraid of something much worse.

That really helped me put this in perspective. She was right. I am OK! My family is OK!

Another interesting note: after we had been talking a while she asked if I had pictures. As she flipped though them, she keep say that she barely recognized me. Then she got to one where I was wearing sunglasses as the only difference from the picture before. Suddenly she said she could see me in the picture. I had been using the glasses to hide behind and make it harder to recognize me. Oops!
