Wishful Thinking.

To start with, I really like the imagery here.  In an incredibly brief poem you managed to communicate a whole thought and do it prettily.  I am not used to liking haiku, perhaps because they are so short that one must struggle to have any depth, but this one is well worth a re-reading. 
The subtlety also appeals to me.  It is a frank statement, not a melodramatic, frilly and 'poetic' revealing of all of the speaker's woes.  With this format what is said is believable as a feeling and elegantly stated.  Relevant, and pleasing to the ear. 
Further, the rhyme promotes a flow as well as the overall meaning.  There is a concept called fluency, which holds that human minds feel better with rhyme.  Matthew McGlone and Jessica Tofighbakhsh proved via a study that people judge aphorisms to be more penetrating if they rhyme.  So I congratulate you on managing to fit a rhyme into a non-rhyming fixed form. 
Finally, the lack of errors, grammatical or otherwise, makes for a smooth reading.  I can find no fault with this poem, and can only praise it.
