Dear Aviv,
I enjoyed reading your blog. Your English is quite fluent even though there are many mechanical errors (alignment, spelling, capital letters, punctuation). You should try to use spellcheck whenever it is available (like here).
You chose a good book about coping with a health problem that influences a teenage girl's life. By doing the blog you had to go deeper into the theme.
Good Work!
Your final grade is 88.
Yours,
Karen Noll Stanger
