I appreciate your efforts in seeking help in this situation. Self-harm is very dangerous; it indicates an underlying Psychological disorder.
It is strongly advisable that you talk to someone about this.
In the first case, self-harm is going to only harm you; it is not going to help you in anyway. Finding practical solutions to problems is more important than grieving over it.
Please speak about the problem or stress
to a professional counselor, a doctor or even your mentor or a close friend.

I wish you quick recovery and happy life.
