I'm sorry to hear that you are struggling right now. It sounds to me like you might be in your teens. Have you spoken to your parents about this? I think it's very important that you see a medical professional to start, who can rule out physical causes, and then see a therapist. If this doesn't seem feasible to you, can you reach out to a counselor in your school? The Social Worker that worked in my daughter's school was very helpful when she was struggling. But please do reach out to someone.
