This song uses metaphors to explain what happened and how they feels after a bad relationship breakup.
Thunder, lightning, those are rough times. Chains, the attachment the couple has. The bitter pill, the inconvenient truth. Rolling into the sea again is looking for someone else, another partner. "You're by my side, but are you still with me?" refers to the fact that the person is physically there, but not emotionally or with support. Other metaphors, like the colored animals, show attachment.
