Who is me???

I used to know me so well.
I used to be free and now
Who is me?

I used to know all the answers
But now what is going on here?
Nothing is clear,
Cold fear…
The frontier…I see the frontier…

I used to be free
But who chained my heart
And buried the key?

Safe side…shield…
Something in my blood boils…
My soul recoils.

I used to know me so well…
But now when I close my eyes
To see, there she comes…
This sad banshee…
