Stone lyrics

I've got a stone inside me I don't have a heart I've got a stone inside me I hide behind it all Inside me Mountains are moving Inside me My world is turning I'm lukewarm I'm not cold And i shine pale light They've taken away my colours I'm left with grey The saddest shade I really want this sorrow to end I've got a stone inside me There's no way to see it from the outside I've got a stone inside me There's no way to see it from the outside Got mirrors in my eyes
