It's hard for people to get help for themselves because they are embarrassed or afraid. Many people are scared of being judged or getting rejected so they don't want to get help. If someone asks them if they need help, they might say yes but otherwise, they wouldn't ask unless they know that nothing would happen to them, but even then, they would rather not ask.
