Wow...I'm so sorry you having to deal with this right now.
It can be so easy to get caught up in self-beating talk of what you could have done differently, but all that does is make you feel worse.
Can you take a step back and see what lesson there is to learn from this situation?
If you do see your friend, maybe you can ask her to pray with you? Religion is what first brought you together, so go back to the strong foundation you both share and start from there??
I'm sorry if this doesn't help. Just know I read your story, and you are in my thoughts.
