HOW DO I AS A 11 YEAR OLD GIRL OUT (im a 16 year old)?

Don't worry about being imperfect because like the first answerer said, no body's perfect. I'm scared of heights myself so I can't help you with that one lol. As for the dark, try sitting in a room with the lights off. It's not so scary and nothing will jump out and get you, I promise. As for the being close to a girl* (a guy in my case), I understand where you're coming from. Just don't do anything you're not ready for.
