repression
The truth is that life can sometimes hurt us, so if we are angry for some reason and do not express our feelings, these suppressed feelings are buried in our body and may appear in the form of high anxiety, depression and even physical illness in the future.
Suppressed emotions are like poison that spreads more and more powerfully in our mind and heart, the longer they are released, if we accept them, they will lead to our personal growth and success, but unfortunately, most of us are afraid to face our emotions, especially if they are associated with bitter experiences.
