I'm really sorry to hear that you're experiencing this, 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 guidance to help you through this challenging time.
Hearing voices that instruct you to harm yourself can be a sign of a serious mental health condition, such as schizophrenia, or it could be related to other mental health issues like depression, anxiety, or post-traumatic stress disorder (PTSD). It's crucial to seek professional help to get an accurate diagnosis and appropriate treatment.
Please consider reaching out to a mental health professional or a helpline in your country. In many places, there are hotlines and organizations that offer support for individuals dealing with mental health crises or self-harm thoughts. Don't hesitate to ask for help – you don't have to go through this alone.
