I Dont Like Seeing People Being Left Out

Its kinda my unwritten life story, being leftbehind. People around me would just move on with their lives and be happy whether by having soo many people around them to care about them or by getting into relationships, etc etc and im yet to be at least happy as half as them.. Its kinda sad as these people we used to eat, drink, sweat and even bleed together (football).. Well, some people are just destined to be miserable for all their lives and the closest they can get to being happy is by watching others move on... At these timea id remember a quote i read and it goes like this "God gives his hardest battles to his best soldiers"... It really gives me strength, however momentarily...
