Is Loneliness a feeling or an existential fact/phenomenon?

Fools mistakenly confuse what they feel with true emotions which are essentially anger, envy, grief, and joy. Loneliness is not an emotion. It's a state of being prompted by a need to be sociable as Man is a social, not solitary, animal. No matter how much an individual meditates on the nature of loneliness, his loneliness does not go away if the need to be with other humans, preferably with those who understand and accept him, is not met, just like you don't meditate away feelings of hunger and thirst. They have to be met. Of course, one does not die from loneliness right away. One dies a slow death. Biological needs are always more urgent than social needs. One can suppress the social needs to some extent, but they don't disappear. A human is diseased if he does not feel a need to interact with his fellow humans, if he never feels lonely if being cut off from his kind.
