Yesterday I was feeling really frustraded and very angry and stressed so I cut myself not very deep but still enough to leave some really nasty marks. Today I went to school with a t-shirt because it's hot over here I was really trying to be careful to dont anyone see the marks on my arm, yet I catched my best friend looking at my arm and I panicked . She didnt say anything but i'm really ashamed of what she could think of me. So do you think I should go to her and explain why I cut myself? I dont want her to be worried and expecially I dont want her to tell my teachers because they would tell my parents and I dont think I could deal with that.
