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.
I think it's a rather common thing among self-injurers because as you pointed out the pain is an important part of why we do what we do.
