"Hugs oneself" is an expression that conveys a sense of self-satisfaction or smugness. The antonyms for this phrase could be words such as self-doubt, self-criticism, self-censure, or self-reproach. When we hug ourselves, we are essentially congratulating ourselves for some accomplishment or feeling good about something we have done. However, if we doubt our abilities, criticize ourselves too harshly, or fault ourselves for our shortcomings, we are hardly likely to engage in any self-hugging behaviors. Therefore, antonyms of "hugs oneself" could indicate the opposite of self-acceptance, kindness, and compassion towards oneself.
