I'm just wondering what age other people began SI? I cut for the first time in September, and I'm 24 years old...I'm prob not going to stop anytime soon either. My therapist is concerned because it's new for me, but also because i'm not the typical age where behaviors like this start. We're trying to find out why I started, I've got some ideas about what triggered me, but it's something I'll prob never know. Anyone have any ideas or similar situation?
