SS..I know the song very well..in fact I listened to that whole album non-stop for a year..it's a beautiful song indeed. I'm so sorry for your loss..we can none of us understand the depths of darkness a person must be in to take their own life. I have to believe that there is a greater power with them at such a time and certainly now as their souls begin the road home to healing & light.
My prayers are with all who love Karena..may you comfort one another..come together in understanding and find peace.
God Speed
