Verse 1:
You can't control your mind, you're lost in confusion
You're feeling defeated, you're feeling defeated
But you're not alone, we're here to help you
We're the sisters, we'll never let you down
Chorus:
No mercy sister, we're here for you
No pain, no gain, we'll never let you fall
No mercy sister, we're here for you
Through the darkest nights, we'll always be there
Verse 2:
You've been through hell and back, but you won't give up
You've been through so much, but you won't give in
You've been through the worst, but you won't give up
You're not alone, we're here to help you
Chorus:
No mercy sister, we're here for you
No pain, no gain, we'll never let you fall
No mercy sister, we're here for you
Through the darkest nights, we'll always be there
Bridge:
When the world is against you, and it seems like it's too much
You can call on us, and we'll come to you
When it all seems hopeless, we'll never give up on you
Because we know your worth

No mercy sister, we're here for you
Through the storm, we won't leave you alone
No mercy sister, no pain no gain
Through the darkest nights, we'll always be there for you
Outro:
We are the sisters, standing strong for you.
