It's interesting that you found this poem so sad, because I actually didn't write it to be depressing - more as a response to the idea of happiness being one's only purpose in life (Hence the title "I Want to be Happy"), as well as an idea for a science fiction story. Of course, the idea of someone being completely satisfied with artificial happiness is a bit chilling, but then again, they don't know the happiness is artificial, so... (this sounds like a question that would be introduced in philosophy class, doesn't it?)  Anyway, thank you so much for responding and giving me something to think about.

Gosh... that... hurt.... its so sad. Its really bitter-sweet in some ways, but to me it's just sad.
