I don't want to be ostracised and left out

I feel like I distract myself from a lot of things that go on in my life. I try to hide or mask away the confusion or unhappiness with friends and laughter. Yes, I am genuinely content with my circle of friends but there are just times where one feels inferior. Why can't I be popular? Why can't I be pretty? Why can't I be intelligent? I know these things are far from what matter in life. Things that should matter are values and beliefs and sincerity but I can't help but to think about these factors about my life. They affect your self-esteem and social circle so much. I'm so afraid of doing something that will cause unrest in others. I don't want to be ostracised and left out. Everyone wants to feel included and feel a sense of belonging. I know i'm not the only one that feels all this but at the same time, I want to be all these things. I'm scared but I don't show it to others. I want to be loved and to love others. I don't know how or what is my true self anymore. I'm scared to be real. I'm scared to be judged. I'm scared of being different but i hate being typical. I don't know what to do.
