Fix me?

Dean is a nineteen-year-old boy who has psychological and emotional problems. He can't express his feelings properly and all he ever felt were only the bad emotions. Dean is acting really cold and can't do anything about it. Life does not wish this boy much. Due to the fact that he never expressed much emotions like gratitude, happiness, etc.. his parents never paid much attention to him. When Dean was little, they tried to deal with it and asked professionals for help but they told them it needs time and there was nothing they could do for them. Dean only sees the dark side of everything and never the good, his parents didn't like that. Therefore, his parents were more interested in Dean's younger siblings. Dean is the oldest of all five children and also one of two boys. However, one day Dean meets someone who catches his eye. Out of nowhere he starts to feel all the positive emotions somehow but it seems strange to me because he is not used to it. This person swears to him that he will fix him... But why did he have to do what he did?....
