Analysis of Pins and Needles

My heart beats in time to our first song.
It's always the same, and I never get the words wrong.
I keep saying that I don't have a problem.
But I know I'm only fooling myself.
I sit in the dark, my tears glittering in the moonlight.
My blood ran cold long ago at the vacant sight.
I don't know how you caught me, but don't let go.
I know we belong, but how can it be so?
You left me alone, and now I'm so confused.
I really want something to happen; I just don't want to be used.
Maybe this will work out, but you need to tell me how you feel.
Until then I'll wait, sitting on pins and needles.
