This is not a problem you can solve. Your friend would be best served by consulting a mental health professional. Suggest that they do so. Hopefully they will take your advice. There’s very little else that you can do.
Sometimes people feel this way when they are depressed or have problems in their lives that they don’t know how to solve. It’s unclear what’s wrong but no matter the problem, treatment could help. Your best course of action is support and encouraging them to seek help.
You might also consider reporting your concerns to the guidance counselor or another trusted adult. Another option is to tell the parents or your friends’ parents. It is always wise to reach out for help. Avoid attempting to “fix” this on your own. Professional intervention is needed. In the event of an emergency, call the authorities. I hope this helps. Thank you for your question.
