A few things. Usage of lowercase i instead of capitalizing it when it's used. Is that on purpose or typos? Also, check your contractions and make sure you use apostrophes where necessary. (I'm kind of big on correct grammar, so ignore me if you'd like).

Very heartfelt poem. I wish my sister and I were so close.
