When we say we are "engrossed by" something, it means we are completely absorbed and immersed in that particular thing. However, there are certain antonyms that can be used to express the opposite feeling. If we are "disinterested" in something, it means we lack interest, enthusiasm, or concern for that particular thing. On the other hand, "distracted" implies that our attention is divided and we are not fully engaged in what's happening around us. Similarly, "indifferent" refers to a lack of any emotional response or interest, while "bored" means to be uninterested due to a lack of excitement or stimulation. These words can be used as antonyms for "am engrossed by" depending on the context.
