Please help?! Serious situations :/?

Slitting your wrists does NOT achieve anything. There are much better ways to face and deal with your problems. You need to sit down and talk to your counselor. I doubt that they will tell your parents, if you tell them not to. As they need to maintain your confidentiality. Wrist slitting usually indicates a deep seated issue. Its a sign of self hatred and nonacceptance of yourself. Accept help.
