If you pretend to be someone your not to make people like you. And you have to be different for them to like you and they don't then they aren't a real friend. So just be yourself and i promise people will love the real you! So please be yourself.
Just hang on for tomorrow. Just because today is a terrible day doesn't mean tomorrow won't be THE BEST DAY OF YOUR LIFE. You Just gotta get there. Hebrews Jesus who is the same God forever, will NEVER forsake you, no matter how you feel.
