I Last chose to do it last week.
Failed a retake exam, all the stress mounted up all at once, thought I would have no future because I failed this one exam. Cut the fuck out of my arm... 9 deepish across my lower arm.
However I last subconsciously did it
two nights ago (AKA, I did it in my sleep... I sleep cut or what ever you wanna call it) If I don't do it tonight, its a record for me
