what do i tell my cousin when she tells me she wants to start cutting like i do?

There is a lot wrong with this...

Your cousin seems to think it's in some way "cool" to cut yourself because tu do it. Stop talking about it, do something so she doesn't think it will make her cool.

Also, get help if you're cutting. Not healthy, obviously.

STOP FREAKING CUTTING YOURSELF!

what trainofdoom said.

y do u cut your sif

Same thing happened to my bro with my sis I just hit her if I saw her do it

I completely agree with PaisleyPark.

tu need to talk to her about the dangers, where it can lead you. tu have to tell her that tu do NOT cut because it's cool, but because tu seriously, seriously feel the need to. Convince her that it's a bad, bad idea, and that tu wish tu never started, because it's not healthy.
