Explanation:Repression is a pyschological defence mechanism that occurs when one pushes back all the painful thoughts and undesirable urges so that they are absent in their conscious mind. This helps the person become less anxious.

The painful thoughts or desires are pushed back so that one will not be aware of their existence.

It not about avoiding an issue but a person actual hides these thoughts in away that they literally don't surface into their conscious mind.

However, eventhough the person may not be aware of these thoughts or feelings but they can still manifest themselves in one's own behavior and relationships.

For examole If someone was betrayed by the people he trusted the most at the young age they may find it hard to trust people when they are older.
