We all have strengths and weaknesses. The most popular girls can be the most insecure and at the most risk. The nicest guys can be at risk of continuously getting rejected by people unwilling to be nice in return. The smartest kid can be socially awkward and consequently, secretly sad or depressed, as social acceptance is amazingly important to us teenagers. Stuttering further complicates the matter.
People can be smart, cute, big, tall, black, white, whatever.
Each of these characteristics brings pride as well as insecurities and fear. When stuttering is introduced, their whole life can be turned upside down. In addition to their current resume, they now have to deal with a handicap which daunts their every move. I imagine that those whose stuttering develops a little later have the greatest shock, as they would probably have a hard time dealing with it. As you might have guessed, I'm pretty young, only 15.
