I'd say to work on letting this friendship go. Please don't contact her for ANY reason. This is hard, I know, but the bottom line is that she is a direct threat to your own safety. She thinks she is trying to save you, but the truth is that she is overreacting because of her own past. She caused you to leave your apartment in the middle of the night (not the safest thing to do, even if you live in the best of neighborhoods), and being hauled off to the ER in the back of a cop car could have spun you off into a terrible episode (I know that's what it would have done to me).
Sending a self-pity text about deserving punishment isn't a reason for someone to lose their freedom and be hauled off to the ER! (OK, I think that we can agree that deserving punishment is along the lines of self pity, right? I struggle with this, too.)
The bottom line is that she doesn't have safety issues like many of us with PTSD do, and she will never know how much we struggle just to have this basic need met. I know I go on and on about the safety thing in post after post, but it's true. Most people don't have a clue about our safety issues, nor will they ever. They take for granted their sense of safety because it has always been there.....its so second nature to them that they probably don't/can't even acknowledge that they even feel "safe", because they have never had a true sense of feeling "unsafe" (at least not in an ongoing sense).
Sorry for rambling, but please, don't contact her again. She is not a safe person.
