The phrase "feeling at home" denotes comfort, familiarity, and belongingness. Its antonyms, however, refer to the opposite - a sense of detachment, unease, or being out of place. Words such as unfamiliar, foreign, aloof, and uncomfortable all describe feelings that are the opposite of being "at home." Other antonyms of "feeling at home" could include words like unsettled, estranged, isolated, and disconnected. These contrasting perceptions might come from a lack of connection between oneself and the environment, or can be a sign of discomfort with the people around us. Regardless of the cause, the antonyms emphasize the importance of feeling comfortable and welcome in our surroundings.
