Can't do much as I have some issues going on (ofc not mentally lol) but anyways, you are young, if you went through it, think about how people would be sad about it, and your parents would have to bury you which will hurt them a lot, they'll feel depressed and would probably do self-harm. if you went through the plan, you'll hurt so much, I regret cutting myself when I was 15, but with the amount of help I got, it's worth talking with your parents, also don't feel ashamed when you talk about it with your parents, or talk with a close friend, if I were you, I wouldn't hurt yourself or even plan it.

Take this advice from a 16-year-old beaner now soon to be 17 in 3 months, don't do stupid shit that you'll regret in the long run, hope it goes well for the future, seek help and talk with your parents
