Dear Prudence,
I have very noticeable and semi-recent self-harm scars on my upper arms and thighs, and with the weather in my city warming up, I know tank tops and shorts will expose them to people around me. My friends are unaware of my cutting, and I’m really anxious that one of them will ask why my bicep has a bunch of healed-over red marks on it. I don’t want to scare anyone who asks, or possibly trigger someone else who’s had traumatic experiences with self-harm, be it their own or someone else’s. Is there a gentle way I can tell the truth without igniting worry? Is it better to lie and not risk hurting the people in my life with this information? If no one asks at all, do I have any obligation to explain why my arm has so many scars, where last summer it didn’t?
