The phrase "freaked out on" is commonly used to describe someone who has become overly anxious, panicked, or upset. To describe the opposite of this state, we can use antonyms such as calm, relaxed, or composed. Other potential antonyms might include serene, tranquil, or peaceful. By focusing on these opposite states, we can help to reduce feelings of stress or overwhelm, and cultivate a sense of peace and stability. Whether through deep breathing, meditation, or other mindfulness practices, we can learn to control our emotions and stay grounded even in challenging situations.
