Chances are, this woman is under mental health services. Therapy doesn't cure suicidality over night, and even if you are cured, if the triggers are strong enough, chances are that you will resort to your favourite methods of coping. For many, that is suicide attempts. Though, I do suspect that this woman knows that two floors won't kill her, and its more of an "advanced" form of self harm.. Also, when you're in the mental health system of this country, you quickly come to realise that the best way to get treatment when you're desperate for it is to "scream loudly" - ie, do something dramatic. There are a couple of very good crisis houses in your area btw, which I wish the NHS would make more use of..
