Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde. . . . I became, in my own person, a creature eaten up and emptied by fever, languidly weak both in body and mind, and solely occupied by one thought: the horror of my other self. Which theme best connects to this excerpt?

The speaker describes being physically and mentally weakened by the thought of his “other self.” This shows the distress caused by hiding or living with a secret identity, so the best choice is “Living with secrets is painful.” The excerpt focuses on inner suffering, not friendship or wisdom gained over time.
