Cover art for Winter Passing lyrics by Taking Back Sunday

I think this song is about someone in love with a depressed person. He tries hard to save her from her depression with everything from "prescription pills to diamond rings" but "nothing seems to stick".

Probably because of her, he begins to sink into depression himself, but he tries to hide it so she doesn't have to "clean that up". He's trying to remind her that he's still around, still "alive", but he knows that's a lie.

They know that the relationship is bound to fail, and Jenny wonders how he will remember her - as someone always depressed - or if he will try to erase every memory of her.

In the end, he probably leaves her because he can't take trying to save her and failing anymore. Maybe he does it to save himself. He's racked with guilt, but he knows he has to leave or die, so he doesn't want to hear her pleading with him to stay, or telling him that she loves him. He leaves, never to come back, and reminds her that he already tried everything he could.

That's just my opinion, but this really is my favourite song ever.
