Lyric discussion by Flibbertiggebet 

It comes across as depression or loneliness and the vocals contrast with the music beautifully, the parts when she sings "I can see it coming from the edge of the room..... can you see it coming now" it's like a half-hearted fanfare in the vocals as if she sees hope but realises there is no point and "breaks down again". The fact that the lyrics change at the end seems pretty significant "Smiling in the streetlight .... I can see it coming now" suggests that she has tried to rid of this loneliness/depression and has failed and she realises she is doomed to it again "My old familiar friend" may say that she's had this feeling before and knows it well, also the music calms down here and becomes more placid this could suggest that she has lost hope. the last two lines are sung higher and louder like a shout showing complete frustration and anger possibly at herself for letting herself break down or it could be the beginning of the breakdown it's self....

Wow I just kind of kept going didn't I. sorry it's such a long comment :D
