Watching the film, I couldn't quite make out the lyrics, so I listened to it on my stereo and then looked up the lyrics here. They are pretty intense (yet also melodramatic):
Make a joke and I will sigh and you will laugh and I will cryI can understand why generations of alienated teenagers have felt such a strong connection with the song. There is quite a thoughtful discussion of the song here. I can't decide if the closing lines are chilling or simply over the top:
Happiness I cannot feel and love to me is so unreal.
And so as you hear these words telling you now of my state
I tell you to enjoy life I wish I could but it's too late.
