It's hard when friendships are involved in this - although I think she has the right to be upset - Maybe she is afraid for you, self-medicating or stopping medications are important issues. Maybe it scared her that you stopped your meds and the only way she knew how to react was with anger. Give her time. I rewrite and rewrite lots of things. Thats always good, sometimes when your upset you write things you really dont mean, so its good you went back after you settled down and made sure it was what you really wanted to say.
