Analysis of A letter from heaven

When tomorrow starts without me,
   and I'm not here to see.
If the sun should rise and find your eyes,
     filled with tears for me.

I wish so much you wouldn't cry,
     the way you did today,
While thinking of the many thinks,
     we didn't get to DO.

I know how much you love me,
    as much as i love you.
And each time you'll think of me,
    I know you'll miss me to.

When tomorrow starts without me,
   don't think we're apart,
for every time you think of me,
I'm right there in your heart <3
