My Dream Comes True and More

This story is about a girl (you) who is in her second year of university. Ever since she was little she dreamed of being a singer and had shown talent. She brought her own guitar during high school and taught herself to play. Since then she's been playing and singing to herself. Oddly no one had heard or seen her play. The only people who saw her were her parents and her boyfriend. But she recently got her hurt broken by her boyfriend of 5 years. They have been dating since they started high school and caught him with her best friend in their bed doing the nasty. Witnessing, she bursts out the room and runs away. She runs to a nearby park with her guitar and starts to sing. What happens to her now?
