unwell
sick / ill / distressed / unhealthy
Adjective
This term serves as a polite, understated way to describe illness, often used to avoid specific details about a medical condition. It carries a softer tone than sick, making it common in professional or formal settings when requesting time off or explaining an absence. When applied to mental health, it describes a state of instability or distress. In this context, it suggests a temporary deviation from a healthy psychological state rather than a permanent diagnosis, often implying a need for recovery or support.
