This song is about knowing that no matter what happens, there's always a bottom, and once you reach that bottom, the only way to go is up.
"Don't stop the raing from pouring down, let it wash the pain where it can't be found" is saying that we have to suffer through the pain in order to get where we need to go because if everything is always handed to us and we don't have to struggle, how are we going to learn to appreciate what it is that we have.
