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, understanding, and assistance.
Feeling the urge to hurt oneself or engage in self-harming behaviors, such as hitting one's head on a wall, can be a sign of underlying emotional distress or mental health issues. It may be linked to conditions like depression, anxiety, or other mood disorders. If you're experiencing these feelings, it's essential to reach out to a professional who can assess your situation and provide appropriate help and guidance.
Remember, seeking help is a sign of strength, not weakness. Don't hesitate to talk to someone about what you're going through so that you can get the support and care you deserve.
