Adolescence is a time of change and confusion.
Kids look at their peers and rarely feel as good as what they see, seldom feel as competent as their peers appear, and generally feel inadequate. Their self esteem is damaged because they interpret information through a filter and are not properly equipped to determine its validity.
The young person feels as though he is full of holes, something is missing that he doesn’t believe is missing in other people, he feels a void he is certain is unique to him. Alcohol and other drugs seem to fill those holes, quiet the confusion of adolescence, and helps promote the idea that “I am invincible” and, for the moment, it makes the adolescent feel good.
