I know how she feels.
Day one, Start over again.
Meaning trying to find yourself again without the other person that your use to being with.
Barely making sense, for now I'm faking it.
She is getting up everyday just like she is expected to and is continuing on but it's not what she wants it's what she is expected to do.
From Scratch, begin again.
I can really relate to this part it's like all that time was wasted and you have to Start from the begining with someone else and she's dreding it!
And that's why she says I as I and not as we b/c she realizes her future will be without the person that she loves!
