In addition to the desire to have children, Lexi has known many limitations in her life. She is an incredibly big Harry Potter fan and had always wanted to go to Universal Studios in Florida. But since she lives in Indiana, this dream also implies that she has to travel a long way.
With a body weight of more than 440lbs (200kg), she could not book a plane, and she would not even be able to ride in the amusement park rides. Travel was no longer an option for her at that time. Her dreams faded with no hope that they would ever come true. And then Lexi had had enough. It was time to take action.
