Madi saved Clarke by being there for her. My take on it is she was unable to connect the bunker or the ring so she assumed everyone was dead. At that point she probably contemplated suicide, but found Madi while gathering supli to do so. By finding Madi she had someone to talk and care for giving her purpose to live.
