I live for the phone I die for the mail   I took your picture right off the nail   And put it right by my bed   So, I could see you instead   Of the darkness of night      I hold conversations with you in my mind   They only tighten this knot deep inside   And the aching won't end   'Til I hold you again, if I only survive      Why did you have to go?   Why am I missing you so?   One heartbeat at a time   I'm going out of my mind   Missing you, missing you      I started a letter, I stared at your name   There wasn't a line that didn't echo my pain   There was no sound at all   But the slow lonely fall of an unspoken tear      Why did you have to go?   Why am I missing you so?   One heartbeat at a time   I'm going out of my mind   Missing you, missing you      Life may take us   In different directions   But I always end up deeper   Deeper in my true affection      Why did you have to go?   Why am I missing you so?   One heartbeat at a time   I'm going out of my mind   Missing you, missing you
