I dont get it why

It been a while since i keep on courage and be good with my self behavior to all people around me. I dont get it why mom keep nagging at me everyday. Why must me? Misplaced thing also me. Mischief things. Also me. Arghh im tired of all this bad ass. My sister treat me like nothing. Like im not someone exist. Am i? She should think what have i done to make all thing goes to complete on her. Her title and evertythibg. Why cant she be proud of all? She is just wonderful in every eye but people dont know how pain is it feel inside my ass. Im just tired. With my thyroid here in my neck i just cant control my self anymore. Why cant this feeling just fade away? *sign .
