The phrase "am ill with" generally describes a state of being unwell or sick. However, there are several antonyms or opposites that can be used to describe a contrary state. For example, "am healthy" or "am well" can be used to describe a state of good health. "Am energetic," "am strong," and "am lively" can be used to describe an active and vibrant state. Additionally, "am fine" or "am okay" can be used to describe a state of being in full or reasonable health. It's essential to be aware of these antonyms as they allow people to accurately describe their state of well-being and help doctors determine the best course of treatment for an individual.
