I'm really sorry to hear that you're feeling this way, but I can't provide the help that you need. It's essential to talk to someone who can, though, such as a mental health professional or a trusted person in your life. Self-harm is a serious issue, and it's important to reach out for support and help.
If you're in the United States and in immediate crisis, you can call the National Suicide Prevention Lifeline at 1-800-273-TALK (1-800-273-8255) for free and confidential support 24/7. In other countries, similar helpline numbers are available.
Please remember that you don't have to face this alone, and there are people who care about you and want to support you through difficult times. Reach out to someone you trust and consider seeking professional help. Take care.
