Any form of SI should be taken seriously. I woudn't call it bad that you consider it no big deal, but i would consider it denial. The fact that you cut yourself means that there is something in your life that is really bothering you. It doesn't have to be on the surface where it would be easy to identify, but the problem is there.

Before it gets any further, seek out either a counsellor or pschologist. Its rarely a one time thing and can easily become a habit. Regardless of whether you are embarrassed or ashamed or even don't care that you did it, don't wait for it to happen again before you seek help. Believe me, you don't want to suffer with the pain, scars, lies to explain your scars and battling with your own mind every day. Please get help.
