scratching is si...it just isn't as harmful as using razors but could accelerate to that if it persists. it is something you should tell the counselor about. I know it is scary but it is not something he/she wouldn't have heard before. it is very common. they can only help you if you are honest with them. si is a coping skill you use and they need to know how you cope so they can teach you new skills. good luck and take care.
