and just like you, I am ready to take on these challenges.
Great first paragraph, but the ending seemed weird.
So you used the second person for any/every nurse? I'm sorry, but I'm can't seem to express what I think is wrong with the ending.
Anyway, the second paragraph could start with a better transition.
I think this should be a colon instead of the semicolon:
I was amazed by everything
: the hospital, the doctor, the blood counts, the nurse.
Now that I've read the whole essay, the first paragraph seems really detached from the rest.
