Complaints become useful only when they lead somewhere actionable.

Complaining serves a real purpose up to a point: it names a problem and often relieves pressure. Past that point it becomes a way of engaging with the problem that never touches it, and repeated complaint tends to entrench the feeling of helplessness rather than relieve it. The test is whether anything downstream changes.

Allow yourself the complaint, then ask what it implies you should do. If nothing, ask whether you can accept the thing instead. Either exit is better than the third loop.
