my mind tends to do that when im hell bent on being distructive or a danger to myself.i dont know if that was the case with u, but its like your minds trying to tell u something u need to listen to.most people dont control thier own thoughts hence we tend to suffer from negative frames of mind, instead of correcting the downward spiral of self critical thoughts or self serving thoughts we use to justify our right to feel like hell.
it might be worth writing down what those words are shouting out about,it could be a self preservation tool your mind had come up with so u take stock of what u are thinking and feeling.good luck.
