What rhymes with happy and is an antonym of happy?

This is a bit of a tricky riddle! There isn't a word that perfectly fits both criteria.

Here's why:

* Rhyming with Happy: Words like "snappy," "tappy," or "flappy" rhyme with happy, but they don't mean the opposite of happy.

* Antonym of Happy: Words like "sad," "unhappy," "miserable," or "gloomy" are antonyms of happy, but they don't rhyme.

So, there's no single word that does both!
