Self-Injury Support Group
Whether you or someone you know or love struggles with self-injury, this is the community to discuss your experience, find support, meet others going through the same, and get advice on how to stop. Working together, we can help find alternative coping skills to reduce the urge to self-harm.
What do you want your friends to do? Not associate with you because you cut? Confront you about it? Turn you into the Counselor?
You sound upset because you've not been "caught".
If you need and want help, then go to your parents and have a conversation about seeing a Therapist or go to your School Counselor and ask her to help you talk to your parents.
