Life's Struggles

I used to cut,
But I wasn’t a cutter.
I used to be addicted to pain pills,
But I wasn’t a druggie.
I used to be ignorant of the world,
But I wasn’t stupid.
I used to look upon someone and judge by what I saw on the surface,
But I wasn’t judgmental.
I used to go through life care-free and innocent,
But I wasn’t a child.
I used to think I knew what love was,
But I didn’t know you.
I used to think I could get over my depression,
But I didn’t realize just how hard a struggle happiness is.
If I used to be what I wasn’t,
Who am I?
