闹情绪 is a separable verb (离合词) meaning 'to be in a bad mood, to sulk, or to show discontent' — often used when someone is emotionally upset and acts irritable, uncooperative, or passively resistant because of dissatisfaction. The splitting rule: the verb 闹 and the noun 情绪 can be separated by measure words or modifiers, e.g. 闹过情绪, 闹什么情绪. Use it for temporary emotional states, not chronic depression.
