Is it normal for the new girl to be a nutcase?
A new girl came to our school a couple weeks ago and yesterday she was showing everyone the cuts on her legs,arms,hands,and wrists. She even cuts herself in math class. She said that just woke up with cuts all over her but the cuts appeared to be perfectly straight lines made with a razor or sharp object so they were definitely self inflicted. I have never talked to her before but I'm wondering if maybe I should tell a teacher. What should I do and why does she do this? IIN??
