"Full to bursting" is a phrase that typically describes a state of being excessively full or packed, often to the point of discomfort or overflowing. There are several synonyms that can be used to describe this feeling, including "overflowing," "brimming," "stuffed," "crammed," and "packed to capacity." Each of these terms paints a vivid picture of a situation where something is so full that it cannot accommodate anything else. While these words can be used interchangeably to describe the same general feeling, they each have their own unique connotations that can be used to add nuance and depth to the description of a scene or feeling.
