This is a good story within a powerful theme. Really nice essay substance that isn't used to potential.
1)Para 1: I don't understand exactly what you are trying to say. Think of the possibility of better opening.
2)Para 2:
Drugs and alcohol never interested her; i
Sentence gives a feel of flippancy on the issue of drugs and alcohol. Edit it. You need to mention really 'her character more'. Maybe something funny or unique or beautiful about her. Let us also see the character also.( You need to mention more juicy info. when constrained in word limit.)
3)Para 3: Don't you feel blank and all numb? Maybe that is better than saying, "struck me by surprise."
4)Para 4 and 5: The best part of your essay because you are showing yourself. Your character outline is really clear when you write that I wanted to comfort yet could not bring it up. Yet, didn't this experience made "you realize how much granted we took family for. We forget the most vital part of our life until such an incident happens." By writing, this you show that you have learnt a lesson.
5)Para 6: Instead of "version" write "stages". By the way, please mention which cancer and did you go with flowers to meet him? What was the experience? What did you say and what did you want say which you couldn't convey... Like that. Adds more passion to the essay.
6)Para 7: You could notice her enthusiastic attitude... didn't get this? Either elaborate or usually, it takes people a little time to come out of shell. An extremely traumatic period which leaves a person a little closed up and tensed.
7) Para 7: This para was derailed from the main idea. The question someone who influenced you...
So,
I realized that had I been in her shoes, I would have broken down unlike Kirby who was a different person all together. She was extremely responsible and mature which must pushed a load of her parent's heart. Her positive vibes have left me thinking. I am trying to change. Instead of being a bundle of stress, I am being more positive in my outlook of life.
Hope this helps. :)
