Why are people so afraid to be themselves?

It's easier said than done... Even though we're generally taught to be unapologetically ourselves from a young age, as we grow up we find that many people don't know how to respect someone else's happiness and instead try to sabotage it. Especially if you're noticeably different from the people you're surrounded by. Everyone wants to be liked and respected, that's human nature. We change to fit in with the group because we all seek acceptance and belonging.
