Hi! Sorry, I hope this is the right spot. I'm 16 and for the last few days I've gotten myself into the habit of snapping a rubber band (not too gently) on my wrist (it's frustrating that it's hard to get welts). I did it originally because at work, I get really nervous sometimes. So when that happens, maybe a snap to the wrist will sort it out.
One of my coworkers, whom I really like (as a friend, he's twice my age) noticed this and asked if I had scars and if I was okay.
Last night, I took a paper clip and dragged it on my arm (hard enough to draw blood, but not bad. Just scratches, like less than if a cat were to scratch you). I know that when I was checking the weather, I wondered if I should have my sleeves down, so no one sees the marks, but then how would [concerned coworker] see them? Yeah... I want his attention. Apparently.
I don't know why I did it, and I have skin that scars easy so not sure what'll happen with the marks (but I do not mind scars...). I should be bothered by this? I didn't post this in self injury because I didn't want to offend anyone with an actual issue.

I do not think it's cool and I know it's serious. I think I was genuinely curious to see how much it'd hurt and how much force I'd need.
Yikes.
