Next stop: deserted island

Three days after the accident happened, I've already gone crazy...

Hello my name is Leo, Leo Shan to be exact but my friends called me L. My parents Insisted we went overseas for a holiday...overseas, by plane.
Anyway I'm getting off topic.
I was able to find the captain's notebook and write down everything that happened to me. From day one to day four hundred and fifty or as I thought it was...
Week four
Day five
