Complaining is often an alternative path after failing to express needs. Because directly saying "I need you to understand me" is too vulnerable, complaining is used instead. What are the underlying needs behind complaining? To be listened to, understood, and cared for. At a deeper level, it's about: feeling valued (you take me seriously), feeling empathized with (you're willing to stand by me), and feeling supported (you can help me solve the problem).
