im a 17 year old high school student that is constantly alone. besides my little brother, i dont have really anyone i trust. i get invited to do things with people but i always come up with some excuse or another. and then when i lie awake in bed at night, thinking what a pathetic waste of life i am, and how pathetic it is that i really have no one that truly cares about me, it just makes me sick to my stomach. why am i so inadequate?
