I should be over this by now. I shouldn't feel anxious. I should have known better. I should always be productive. If your inner voice is full of shoulds, musts, and oughts, you are carrying a heavy, invisible rulebook, and every rule you break generates a little more guilt, shame, or frustration. This distortion has a name, should statements, and loosening it can lift a chronic low-grade weight you may not even have noticed.
Should statements masquerade as standards but function as whips. A genuine standard helps you aim at something. A should punishes you for not already being there. The two feel similar but land completely differently: a standard motivates, a should just generates the painful gap between how things are and how your rigid rule insists they must be. And because reality rarely complies with rigid rules, the shoulds keep the guilt coming.
As an overview from the NCBI Bookshelf describes, it is these internal rules and interpretations, not the events themselves, that generate much of our distress. A person ruled by a dense code of shoulds lives in a permanent state of falling short of their own harsh law, even when, by any reasonable outside measure, they are doing fine.
Notice how strange the logic of a should often is when you say it out loud. I should be over this by now, applied to grief, or anxiety, or a hard change, is really a demand that a natural human process happen on a schedule you invented. I shouldn't feel anxious is a rule against having a normal human emotion. Stated plainly, most shoulds turn out to be arbitrary laws you never consciously chose, inherited from somewhere and never questioned.
The gentle correction is to trade the harsh word for a softer, truer one. Instead of I should be over this, try it would be nice if this were easier, and it is human that it is not. Instead of I should always be productive, try I would prefer to get a lot done, and I am also a person with limits. The shift from should to it would be nice if, or I would prefer, or I am learning to, keeps whatever is useful in the aim while dropping the punishment.
This is not about abandoning standards or letting yourself off every hook. It is about noticing when a should is generating guilt without generating anything useful. A helpful test: does this should point me toward a concrete, reasonable action, or does it just make me feel bad about being human? If it only produces guilt, it is a whip, not a standard, and you can put it down.
Watch also for shoulds aimed at other people and the world: they should have known, this shouldn't be this hard, people should be more considerate. These generate frustration and resentment the same way self-directed shoulds generate guilt, by insisting reality obey a rule it did not agree to. Softening them, it would be nicer if, but people are as they are, releases a surprising amount of tension. Rigid rules aimed outward tend to sour your relationships and your mood without changing anyone's behavior, so loosening them is both kinder and more practical.
Many shoulds trace down to deeper beliefs about needing to be perfect, or endlessly available, or never a burden. If you keep hitting the same shoulds, it can help to ask what belief sits underneath, which we cover in the downward arrow technique. And because shoulds are so tied to self-criticism, meeting yourself with more kindness directly loosens them, which we cover in self-compassion.
If a punishing inner rulebook is severe and tied to depression or anxiety, a therapist trained in cognitive behavioral therapy (CBT) can help you work with it, and the NHS lists CBT as a first-line approach. For everyday overthinking, though, simply catching your shoulds and softening the language genuinely lightens the load. We cover the wider family of distortions in the guide to cognitive distortions, and put the full method together in The Overthinker's Manual. You are allowed to be where you are. There is no cosmic rule you are breaking, only an old harsh one you can set down.
