What can be inferred from the passage?

参考解析：

推断推理题。根据文章最后一段第二句“The good news is that the connection between romance and depression seems to become weak with age.”可知，随着年龄的增长，爱情和抑郁之间的关联变弱，即就越不可能在恋爱中迷失自我。故D项正确。A项，“缺爱将导致年轻人更快成长”。文章未提及。故A项错误。B项，“早恋使年轻人与朋友和父母保持亲密关系”。文章未提及。故B项错误。C项，“父母应该帮助他们的孩子意识到抑郁的迹象”。根据文章最后一段第一句“Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. ”可知，父母应该留心观察孩子抑郁的迹象并及时给予帮助，而不是帮助孩子意识到抑郁的迹象。故C项错误。故选D。
