wow thats a tough one..at least your family knows about your cousin (i'm gussing kind of early on?)
but um, if that were me..i'd kind of just hear their story..then make sure they know i'm there for them..
i think that'd be the best thing to do, but that's just me
hope it goes over well :)

if it were me i'd let her know what i went through with it,how hard it is to quit once you start and just because the pain temporarily goes away after you cut its only a few seconds and the scars on your body from the self injury are there forever.and someday she may want to have a boyfriend will she want to have to explain it to him. or if you have a counselor write down what you want to say and let your counselor look at it to see what they think,they can maybe tell you the best way to discuss with your cousin why she doesn't want to follow in your footsteps,if she knows she may question why your telling her its wrong when you do it yourself.i hope you find a good way to help your cousin.good luck!

thanks! you all are really really helpful,
hugs to you both!
thanks again :-)!
