"My Favorite Drug" lyrics

My love, my favorite drug
I thought I had
I thought I knew you
I pictured a world where we never part

But it's been so long
(So long)
Since I had a good day
Since I felt like myself
That I don't quite remember
That world where we never part
(Never part)

Oh joy, why'd you have to leave me
Did I stumble too far down
For you to love me dearly?
The more I try to see it
The more I can't believe
That you existed in me once

It's sad
(So sad)
[?]
That I can't see
Lost all recollection
Of that world that I once pictured
Where we never part
That strange world that I once dreamed of
