Forgive if I'm calling you in this moment
Or: Excuse me if I'm calling you in this (inappropriate) time
But I was needing to hear again
Or: But I needed to hear (once) again
Even for a moment, your breathing
Or: Even if it's just for a moment, (I wanted to hear again) your breathing (/your voice)
Sorry, I know that I'm violating our oath
I know that you're with someone, that it's not the right moment
But there's something urgent to tell you today
I'm dying, dying to see you
