Discussion How hard do I have to cut?

[szk]

I really want to slit my wrists and CTB, however, I'm unsure of how hard I have to do so so it doesn't look like just an average self harm wound, but an accident. To those who cut or cut deep, how should I go about this so it doesn't look that suspicious if that makes sense? Feel free to drop other non noticeable ways as well, anything helps to be honest.
