When Life Takes a Turn

My name is Hannah; I'm 16 years old, and my whole world seemed to change when I met this one person. His name is Tommy, and he is the most popular guy at school. I am nothing compared to that, I'm a dork to his cheerleader girlfriend. I don't even know how to fix things at home, my dad and big brother passed away last year in a tragic car accident; since then my mother found a better guy I guess. They are getting married even! I just don't know how to handle things anymore, but Tommy may be a help,or will he be more? I have a huge crush on him, the courter back, and I don't know if he feels the same. What should I do?
