Is there a reason I feel unfulfilled?

Because as long as I am on this Earth, I fear it may always be this way. Gosh, I can't comprehend why I feel like such a failure sometimes! Am I not doing enough or am I doing too little? Nobody seems to care about this aspect of mine… So, then why do I feel like the World's out to get me?! Is that a means of scapegoating? As if there's nothing else that is really keeping me alive, save for my own wariness towards anxiety? "Woe is me," but that line has been said, billions over trillions of times, that I don't even believe I care anymore to keep count. I'm not done here, but I sure as heck feel some weight crushing on my soul. Simply put, I have to be honest. It's the only way I feel like I'm doing something right.
