I think the beginning is right after some sort of drowning accident. She's being dragged out of the river, she describes the man who helped her as nice... but her lover's been taken away. The rest of the song is more recent events, events that cause her to become more more deeply depressed and manic.
I think the last stanza, the parallelism is referring to her own desire to be at the bottom of the river. Suicide.
