If you know how to trigger yourself into self harm then go ahead. Don't be so lazy. If you are going to slash your wrists then don't expect us to bother picking up the knife and handing it to you. Just remember to slit down the artery rather than across them, because when severed, arteries have a muscular/elastic wall, that helps them contract when completely severed. They cannot do this when simply slit lengthways.
