Once I did something similar, but literally IRL.
Back in the school, at that time I would sometimes sneak away at study-hall and cut my ankles with a pair of scissors. Even with everything "alright and good", my mind was descending into a dark place.
During lunch, me and some randos where talking, and I was a quite down /w a moodswing. Just sick of it all, everything, wanting to really disappear /w my dislike of existence. For some reason, these ppl wanted to talk to me, and giving 0 fucks, I said, "You know what? If you see me at a bridge, I'll be jumping off". I was serious, not my usual (at the time) happy self, and guess what? They automatically assumed I was just joking or non-serious anyways.
It was certainly a lapse of my judgement, but disappointing nonetheless. Tho I was kinda lucky, as /w different people I'd be getting myself all kinds of problems.
Since then I've kept myself under better control, and havnt made similar blunders.
