Sorry, maybe I act differently when around different people. To mind you, I'm not fake. I just have my own comfort zone. That's why I can only be completely myself when I'm with people I'm comfortable with.
What I'm going to say, don't lose yourself in this world. Don't change for anyone. There are people out there who love you just the way you are. Nobody has it easy, everybody has problems. Nobody is perfect and nobody deserve to be perfect. So, before you start judging or criticizing about other people's life, remember everybody is fighting about their own war. You don't even know what they have been through.
