When talking about emotions, I highlight the importance of expressing them consciously, and not erupt. For example, when you are sad, you can talk about it, talk about the reasons for it, discuss the cases, which cause the sadness, and not just cry, or restrain yourself by saying that everything is normal, or demand people to leave you alone.
When you can't express your emotions to your close people and you have not given it a chance to talk about your emotions, moreover, you don't accept when people close to you try talking with you about their emotions, most likely your relationship with them is far from being healthy.
Expressing emotions and talking about them is one of the 10 criteria for a healthy and unhealthy relationship.
In a healthy relationship, people are free to talk with each other about their feelings, both positive and negative.
This does not mean that people do not get angry with each other in healthy relationships. This means that if you are angry, even offended by the other person, you are ready to discuss it with him, you are ready to admit that you are angry, you are ready to talk about the reasons for it, you are ready to apologize for expressing your emotions not ecologically and maybe harming the other person.
In a healthy relationship, we are free to express our frustration, anger, jealousy, and other emotions. As a result the negative emotions come out and do not stay inside us. It may seem strange, but expressing negative emotions directly improves relationships. It may seem even more strange, that it helps to make the relationship more positive, to fill the relationship with positive emotions - love, gratitude, respect and curiosity.
In the case of unhealthy relationships, emotions are suppressed. It is forbidden, it is even dangerous to talk about real and sincere emotions. As a result, people in dysfunctional relations constantly suppress their emotions, which in turn accumulate and become uncontrollable, leading to quarrels, scandals, and, in many cases, violence. Of course, as a result of these, emotional tension does not subside. The situation becomes complicated by the fact that the accumulated negative emotions increase the feeling of shame and guilt, which, in their turn, poison the relationships further.
