Lyric discussion by jadedgypsy 

Sorrow drips into your heart through a pinhole just like a faucet that leaks and there is comfort in the sound but while you debate half empty or half full it slowly rises your love is gonna drown

i think this entire stanza sums up what this song is basically about, although i'm not quite sure why the song is titled such.

basically i think it's talking about how when you're feeling really sad or even slightly depressed, you'll tend to want to immerse yourself in that sadness, or wallow in the misery of the situation. it may be because it can make you feel better cos no one else can understand what you're going thru other than you. (hence, "there is comfort in the sound" of the sorrow leaking into your heart)

and while you're busy deconstructing the reasons for your unhappiness and wallowing in the sadness, you'll gradually close yourself off to the people who love you. and you'll also end up closing yourself up from your loved ones. hence, gradually, "you're love is gonna drown."

and i think the stanza below supports that as well: I wish we could open our eyes to see in all directions at the same time

Oh what a beautiful view if you were never aware of what was around you and it is true what you say that I live like a hermit in my own head
