Self-affected is a term used to describe someone who is excessively concerned about their own feelings, opinions, or appearance. However, there are several synonyms that can be used interchangeably to convey a similar meaning. Arrogant, egotistical, self-centered, and narcissistic are all words that can be used to describe individuals who prioritize their own needs and desires above others. Conceited and pretentious also capture the essence of self-affected, as they imply a false sense of superiority or importance. These synonyms highlight the negative connotations associated with being overly self-absorbed and serve as alternatives to describe individuals who exhibit such behavior.
