You can find a song whose lyrics explain a similar situation that you have. Or simply you can her a song that impresses you. The same thing happens with cinema. When a film is succesful among teenagersit is generally because there is a beautiful love story. We feel indentified.
Feelings also influence the personality of the person and can make people happy or unhappy.
We have very strong feelings and we change very fast. They are important in all our life, but specially in adolescence because we are sensitive. We are developing our personality and it's an important stage in our life that will influence us in the future.
