Rewrite the story

I met her on a train On my way to Baltimore She told me everything Everything a little too much She's gotta a brain tumor She only gotta two months to live She has this peaceful mind The most purest of heart She is not concerned at all I could not fully understand That same month of july We did some bungee jumping We went on a rollercoaster Did some ice skating Tried on some paragliding She loved it all August the third, I believe I gotta a letter from a friend That she had left us We had everything planned To make the most of her time I fell flat on the floor In just disbelief I wondered if God was real Why her?... I asked She was just 18 years old She had some dreams To one day become a doctor Maybe a brain surgeon She was the happiest girl I had ever come across Please, tell me why
