When someone says that someone is "in their feelings," it means that the person is experiencing intense emotions and is emotionally sensitive or reactive at the moment. The phrase is often used colloquially to describe someone who is deeply affected by their emotions, particularly when those emotions may be overwhelming or clouding their judgment or behavior.
Being "in your feelings" can imply that the person is highly emotional, possibly feeling sad, angry, hurt, or even joyful, to the point where it may be influencing their actions, responses, or decision-making. This state of heightened emotional sensitivity might make the person more vulnerable or reactive than usual.
The phrase is commonly used in informal conversations, particularly in the context of relationships, personal matters, or situations where emotions play a significant role. For example, if someone is upset about a recent breakup, and they seem overly emotional or sensitive, others might say that they are "in their feelings." It's a way of acknowledging and describing the person's emotional state at that particular moment.
