I started self harming when i was about 5 or 6. I can rembering using en holders to scratch the skin of my thighs under my dress and on my arms because I was just so bored until i bled during those long meetings we I had to sit still and be silent. It was a release and a distractioin from the boredom and frustration.
I started doing it seriously when I was 20. I hate the scars it leaves on my arms, legs, torso and even worse the disgust and horror that leaps to the eyes of people who see it. My last boyfriend said it just repelled him. The after effects of doing it are utter shame, but at the time I just can't see past how good it will feel to escape the mental torture. When I take the razor to my skin and watch the blood its hypnotic, it stops me thinking of anything else and this will sound insane but it looks beautiful to me at the time.
Of course afterwards, it looks vile as the cuts slowly heal and I have to spend hours sanding them and massaging oil in to try and lessen the starkness of the scars.
