No sir, English does not suck, it is you that sucks. And no, don't copy a sonnet off the internet, your teacher would pick it up right away. You realize, a sonnet is pretty much a song. It's also known as lyric poetry...which are...songs...
Just remember, 14 lines, abba, cddc, etc. Or you could make up your own rhyming scheme as long as it is fluent and flows with your idea.
