When one is trying to quit S/H and when one has an urge:

✗
Avoid hospital shows like casualty and holby city
Tempting though it may be to just "see how hard it is to remove that blade" dont fucking do it
Avoid situations that normally make you cry / get pissed off
Dont listen to sad music

✓
Paint
Draw
Write
Talk to someone who knows how you feel and who can help you
Make something pretty
Watch something that makes you piss your pants laughing even though its really not that funny. Hell put it on yer iPod.
DANCE
Make a list of good stuff thats happened and make one of good stuff to look forward to like seeing friends, and then plan it and grin wildly.
Excercise
Never thought id say it, but tidy. Might take yer mind off it.
And if you must do so, masturbate. "A wank a day keeps the doctor away"
