I cut myself at night
Why would you cut yourself?
I won't tell you, it won't remain a mystery that way.
If you are driven to harm yourself, then you should seek professional help. You could give yourself a serious injury if you are cutting yourself often.
I already told you, I'll continue to do it and no one cares.
It's not ok to hurt yourself in any way, you would die. Talk about your feelings with someone you trust if you don't wanna go to a therapist.
