How beliefs are formed and their impact on emotional well-being

Beliefs are not random thoughts or simple opinions: they are mental structures that condition the way a person interprets their life.

They develop over time, from experiences and reflections that are repeated until they become automatic.

Understanding how they are formed and how they affect emotions is a fundamental step in any therapeutic process, especially in cases of depression.

Experiences shape thinking

Every situation we experience, whether everyday or intense, leaves a mark on the mind. That mark does not come alone: it is accompanied by an interpretation.

For example, if someone does not receive an invitation to a celebration, they may interpret that omission as “they don't care about me,” which becomes a thought that does not necessarily reflect reality.

This type of interpretation usually occurs without being questioned, and accumulates with other similar ones.

Internal language feeds judgment

When people interpret what happens to them, they do not do so silently.

An internal dialogue is generated, a kind of voice that asks questions or makes statements. These are not always neutral.

Questions such as “Why doesn't anyone respect me?” or “What did I do wrong this time?” are already geared toward a negative conclusion, which reinforces feelings of worthlessness or guilt.

The problem is that this type of dialogue becomes the foundation upon which many personal beliefs are built.

Repetition establishes “truth”

The human brain learns by repetition. Just as someone can learn to play an instrument by practicing every day, they can also learn to think in a painful way if they constantly repeat certain internal messages.

In the end, what has been thought over and over again begins to feel like an unquestionable truth.

This is how beliefs such as “I'm not good enough,” “things always go wrong for me,” or “the world is a hostile place” become entrenched.

Rigid beliefs, blocked emotions

These repeated beliefs become entrenched. They function as fixed frameworks from which everything that happens is judged.

A person who believes they are unworthy of affection may interpret any neutral signal—such as an unanswered message—as confirmation that they are not loved. In this way, negative emotional states are perpetuated.

This kind of mental rigidity prevents us from seeing alternatives, generating different responses, or adapting to change.

Changing the way we believe is possible

Beliefs are not life sentences. They can be transformed when their foundations are questioned and new meanings are generated. This requires awareness, intention, and practice.

For example, a person who has believed for years that they cannot trust anyone may, through new experiences of genuine support, build a more nuanced view: “There are people who are trustworthy and others who are not, and I can learn to tell the difference.”

Toward more flexible and kinder beliefs

Replacing rigid mental structures with more open ones does not mean denying the past, but rather reinterpreting it.

Just as a house can be remodeled without destroying its foundations, the mind can also be reconfigured to allow for more well-being and less suffering.

This work involves carefully reviewing those ideas that have limited emotional life and replacing them with others that accompany the present with more compassion and realism.
