Song I heard on radio today

I have heard this song before but today for some reason I listened to the first lyrics and it could not describe more accurately how I feel. Maybe some day I'll feel the same about the lyrics to the 2nd verse - actually when I think about it trust in the unseen is all that is keeping me going - If you haven't heard this song Never alone by Barlow Girl take a few minutes and listen to it

I waited for you today
But you didn't show
No no
I needed you today
But where did you go
You told me to call
Said you'd be there
And though I haven't seen you
Are you still there?

(Chorus:)I cried out with no reply
And I can't feel you by my side
So I'll hold tight to what I know
You're here and I'm never alone

And though I cannot see you
And I can't explain why
Such a deep reassurance
You've placed in my life
We cannot separate
Cause you're part of me
And though you're invisible
I'll trust the unseen
(Chorus)
