Cover art for What the Water Gave Me lyrics by Florence + the Machine

I think it's about suicide. Virginia Woolf committed suicide by filling her "pockets full of stones" and jumping into a nearby river. The line "let the only sound / be the overflow" would point towards the fact that the only thing Woolf would have wanted would be for it all to end; something the water gave her.
