What is love? does it trully exists? and do you believe in love in teen years? can tru love start at 14-16?

I think true love can exist no matter what age you are because when you fall in love you just know it. When you fall in love its the most beautiful thing in the world because that person is all you think about, they arein every breath u breathe, in every thought and in every action. I am only 16 and i have fallen in love and gotten my heart broken but when you are in love its amazing.
