Below, you'll see any text that was highlighted with comments from the reviewer.
I like the fourth line. You admitted that there's many problems and issues in the world, but not enough to complete destroy your life unless you let them do so.
The repetition of the word 'close' in the second paragraph automatically has the reader's mind jump to the first use of the word in the third line. Since the word 'close' (in the third line) was followed by a reassuring statement, the reader automatically assumes that from the eight line on, the message will be positive and the advice will indeed be helpful.
I like how you chose to write poetry and used a rhyming/ repetition scheme. You kept the ideas so that they were more applied to the general, allowing you to share your world experience and what you've learned from it with the reader.
