what you need to do is this:

tell your mom/dad. ik u dnt want to but there the ones that are going to help you.

find out what you feel when you need to cut and when you ARE cutting.
keep track of the feeling, when you do feel it, tell your mom. or best friend. when you want to cut, take all razors, sharp object and throw them away. trust me it will work. you can;t keep them around you, ull have the urge.
Then when you are going to go crazy if you don't cut, tell your best friend. MArk what you feel, when you feel it. DON"T CUT. if you get pass this first time, the biggest urge to cut, then it will be easier to get over the urge.

it will take a while to make ur self. u have to have self controll. it will be hard bt my sis cut her self for 6 years and this is the way, exact way they helped her. it works. but u have to have someone to do it with you. u probably wont want to tell anyone, but u need to. jst think if u cn annouce it to the public then u can tell a friend. tell me how u do, and if u need anything else.

ask your self, why am i cutting ?
then find a reason to take care of tyhe problem of why .
best of lucck :)

find something else to take your stress off. Not hurting yourself! Thats 1 of the worst things to do.

take ur mind off things and relax and stop stressing! go out with some friends, take ur mind off whats making you cut. i wish the best of luck for you :)
