Why is it bad for me?

I just keep feeling so bad I just need that pain to go away
and what is so wrong with cutting I’m not cutting deep enough to
kill myself, so what is the harm in it. Besides like people says
cutting your wrists can’t kill you anyways, so what is the harm in
it if it’s not hurting anyone besides yourself? That’s what I don’t
understand. Why do people care what you do to yourself? I started
out caring what people did to themselves but now I know that if they
what to do it there is no stoping them so why care? I know people
care about me, I do but I just need that one thing that makes me feel
good and if it hurts me and no one else why should someone tell me
that I can’t. So what if people think it’s wrong, it’s right for me
and that’s all that matters. I just need to be okay and when I cut
I’m okay and I get things done because it makes me feel better. I
can really focus after I cut because the feeling of mental pain is
gone. I don’t wish this on anyone but if they knew how good I felt
afterwards they could understand why I feel the need I have to do
it. Just because someone killed themselves because they were so much
worse then me why does it have to be bad for me to do it?
