I went to a therapist only because my mom caught me with fresh wounds, and at that moment I couldn't find any reason to dodge the question. My friends started to notice before my mom, but I told them it was from the pointy end of my desk & was completely accidental. I didn't realize the scar was that obvious, so I wear long sleeve a lot. Some of my closest friends got worried, but maybe were too afraid to ask about it, so they scraped the pointy end of my desk just so I wouldn't "accidentally" cut my arms again. It was kind of sweet actually, but I never got the courage to tell them what actually happened.
