Loneliness is a complex emotional response to isolation or lack of companionship. It can be felt even when surrounded by other people and stems from a perceived disconnection from others, not necessarily physical aloneness. Loneliness often involves feeling sad due to being alone and longing for connectedness or communication with others. It's important to note that it is subjective, varying greatly from person to person based on individual needs, perceptions, and experiences.
