My friend calls herself my "Best" friend. Today she got some very disturbing news from her doctor. We have been friends over 15 years. She did not call me or even send me a message, I found out on her general post on facebook. I am hurt and a bit mad. What is your opinon? I have told her and we discussed it and she said she is sorry, but I am feeling insecure and do I have a right to feel that?
