Most Helpful Girl
Your on your way. Just worry about fixing you because you want to be helped. Change because you want to be changed. Don't change purely for her. When you have your own problems figured out, then you can go back to her. Show her real change, and you might have a chance.
Most Helpful Guy
Keep a day to day journal of all the things you did since, include pictures and show it to her. If that doesn't work, nothing will.
