There are many people who find it difficult to express what they think, but they are more difficult to express what they feel. Culture and education have an important weight in this issue.
Expressing feelings is learned in childhood: that's why children who have grown up in homes where parents did not show affection, where the father never recognized being proud, where the mother kept silent when she felt lonely or depressed or where children had to contain their anger, today they are adults with serious problems to make known what they feel.
One of the reasons why we do not express what we feel is to avoid conflicts. Some believe that this way he avoids hurting another person, and he does not realize that the damage is done when he represses himself. Another reason may be the fear of feeling rejected or believing that they will not understand you. This is solved by improving self-esteem and communicating assertively.

Expressing what we like, what makes us afraid, saying things that generate joy, those we perceive with disgust, express our gratitude or show apologies is what helps us to release and share our feelings, and is the best way to feel good

Suppressing feelings can make you sick. In fact, people who constantly repress what they feel, whether by shame, by shyness or fear, they end up sick. There are some diseases directly related to the inability to express emotions and feelings: stomach pains, ulcers, heart attacks , hypertension and irritable bowel syndrome are some examples.
