Worried---and don't know what to do

The saga continues, and I am less upset with my friend and more worried about her, trying to figure out what is wrong and how to help her even when she is so angry. It's hard. I'm not good with this. I don't know how to help, I am a terrible friend to have. I wish I was amazing at this, but I'm not, at all. I hope The Lord gives me the prayers I need to pray, and the words I need to say to help this all out, because I dont know how to do it on my own.
