Close your eyes, and imagine 5, 10, 15 years from now. You are with your husband and maybe 2, 3 or so kids and your a very happy family, and very self-full-filled and your life is perfect just the way you had always dreamed and hoped, and then your little 5 year old child asks you: "mommy, why do you have all those white scars on your arm?" and then what will you say? I used to take a razor and pull it down real slow and carefully and watch the blood drop out of my skin so that I could see that I am still alive, or so I could feel real physical pain instead of emotional pain. No you can't say that to your child. and even if you do then your child will learn from you and do the same to themselves when ever they are feeling down.
you don't really want that now do you.
