i used to cut, but ive started punching walls instead which leaves me with horribly bruised, swollen, and crippled hands.
my therapist suggested that i punch pillows or my bed. this early in my treatment of this behavior this option wasnt giving me the relief i needed and i would just go back to punching bricks. so she then suggested i go ahead and punch whatever i felt i needed to, but that i wrap my hands over and over again with a thick towel so that there was no chance i would injure my hands/knuckles. for now, this works. and eventually i know ill be able to move onto punching my pillows or just coping with the stress in a less violent and aggressive manner.
