I try so hard to understand you and accept you for who you are, but you make it so difficult. I don't understand why you strive to be you "own person" by constantly doing things you believe no one else has yet to do. Why does it matter if you do it first, or if someone does it after you ? It doesn't strip you of who you are. It doesn't matter if people shop at the same place you do, you weren't the first customer and you won't be the last. You're not the only fan of the person you're obsessed with. How do you think they became famous ? Multiple people love them, not just you. You're not the first person to dye their hair pink/purple/blue/whatever, and you know it. After all, the person you idolise had blue hair before you did. How can you say it's okay to copy the person you idolise, but others cannot "copy" you ? You're a hypocrite and have the shallowest of double standards.
You think what you say, how you dress, and the colour of your hair defines who you are. Are you insane ? You're one of those people who constantly says that it's the inside that makes a person, and yet you want your outside to define who you are. The words you speak are full of lies. You know you're lying, to yourself, to your friends, family, boyfriend, to all the haters out there; you know. No one is going to remember you for the clothes you wore, or the colour of your hair, or the bands you love. You'll always be remembered as the girl-who-tired-too-hard-to-be-"herself". If you were comfortable with who you are, you wouldn't feel the need to constantly be individual, because you already know you are. Clothes, phrases, where you shop, who you're obsessed with; none of that defines a person. Personality does.
That's the saddest thing about you - you're dependent of others to feel individual.
