Brimmed over is often used to describe when emotions, feelings, or actions have reached a limit or overflowed. The antonyms for this phrase would be words that describe the opposite or lack of overflowing or excess. These words could include restrained, contained, moderation, limited, and controlled. Being measured or calm, rather than overflowing or spilling over, can lead to a sense of balance and composure. In situations where emotions or actions may be overwhelming, finding ways to restrain or control them can be beneficial in maintaining a stable and healthy mindset.
