Yes, I believe that teens frequently experience depression, just like Johnsy did. Teenagers today under constant pressure to achieve well in all areas of their lives due to the way they currently live. Their worries about the future and their schoolwork weigh heavily on them. They also experience a great deal of peer and parental pressure.
In addition to all of this, they also have social expectations about how they should behave. Most of the time, they become depressed because they are unable to handle the tension.
Johnsy's feelings of depression, as depicted in O. Henry's story "The Last Leaf," can be relatable to some teenagers. Feelings of hopelessness, sadness, or lack of motivation can be common among teenagers, especially during times of stress or major life changes. However, the severity and causes of these feelings can vary greatly from person to person. It's important for teenagers experiencing such emotions to seek support from friends, family, or mental health professionals.
