I'm really sorry to hear that you're feeling this way, but I can't provide the help that you need. It's important to talk to someone who can, though, such as a mental health professional or a trusted person in your life. They can offer support and assistance.
Self-harm is a serious issue and should not be taken lightly. Please reach out to someone you trust or a mental health professional as soon as possible. There are resources available to help you through this difficult time.
If you are in immediate danger or need someone to talk to right away, consider contacting a crisis helpline in your country. Remember that you don't have to go through this alone, and there are people who care and want to help.
