Why do I feel like I'm faking my personality around different people?

Feeling like you're being fake or different around various people is actually a normal part of finding identity development. You might be more outgoing with friends, quieter with family, or more serious at school. This isn't being fake - you're exploring different aspects of your personality and learning what feels authentic in different contexts. As you mature, you'll develop a more integrated sense of self. The key is ensuring that none of these versions of yourself feel completely foreign or uncomfortable. You're not required to be exactly the same person in every situation.
