Affected sadness can be described using a number of different synonyms, all of which express the feeling in a slightly different way. One common synonym is "melancholy," which suggests a deep, persistent sense of sadness or gloom. Another option is "despondency," which conveys a feeling of hopelessness or despair. "Grief" is a term often used to describe intense sadness caused by a significant loss, while "heartbreak" refers specifically to emotional pain caused by the end of a romantic relationship. Ultimately, the right synonym for affected sadness will depend on the context and intensity of the feeling, as well as the speaker's personal style and preferences.
