I was 18 and it was near the end of high school. We'd just had some sort of event for the seniors, like a dinner or something, and it hit me really hard how everything was changing, like I was going away to college in the fall, as were some close friends. I was also no longer going to be around a male teacher who I was close to emotionally (nothing physically inappropriate ever happened there, but probably emotionally inappropriate), and I think he'd been at the event. I remember that Radiohead's "Fake Plastic Trees" played as I drove home, and it summed up how I felt (and this was back when the song was originally out--yeah, I'm old!). When I got home, I cut my thigh a couple times with a razorblade, and it seemed to help. I think it was a combination of depression and self-loathing (which I guess is a part of depression).

After my first year of college, I didn't really SH. But maybe 4 months ago, partly from depression, some childhood stuff coming up in therapy, and I'm pretty sure from the drug I had recently started (Effexor), the urges came back. I only used my fingernails, but pretty sure it still qualifies. Doing a bit better now (and on a different drug).
