Hi, I'm currently rewriting one of my stories that I wrote a little over four years ago- adding more character depth, detail, and subplot. Personally, I feel like it's really standing out as a story so far, but the second part contains subject matter that may be sensitive or triggering to some viewers. It's divided into 2 parts, and in the first part, the main character gradually goes insane, wheras in the second part, the main character, in order to avoid boring readers by providing the same character arc again, becomes increasingly depressed and begins cutting and talking about suicide. He also deals with finding his friend's hanging corpse, right after his other friend died during a car crash and while his parents are getting a divorce.
With all of this put together, especially it being about a teenager who starts cutting and wanting to kill himself, I'm not sure what the stance would be as far as posting this. Especially due to the primary audience, which would be teenagers who probably deal with depression themselves (I used to be one of them). WOuld something of this nature require a trigger warning/NSFW tag? Or should it be fine to leave it as it is when posting?
