talk to someone.
phone a friend just get youself or your mindstate out the cutting idea.
i was just like you, id suddenly just get this urge to cut and i couldnt stop thinking about it. i use to just be lying in my bed then suddenly i found my self thinking of where to cut next.
I see where you are coming from with the pictures and stories, i use to write songs and play piano but after a while it got so repetitive it stopped keeping my mind off cutting. it sucked...
but if you need someone to talk to im here!
