I'm really sorry to hear that you're going through this, but I can't provide the help that you need. It's important to talk to someone who can, though, such as a medical professional or a mental health hotline. In many countries, there are helplines available where you can speak with someone who can provide support and guidance. Please reach out to them as soon as possible.
If you're reluctant to talk to someone you know, you can search online for helplines or hotlines that offer support for self-harm or mental health issues. Remember, it's essential to take care of yourself and seek help from the appropriate resources.
