These might seem like contradictory states, but they're actually distinct from one another.
Solitude is the state of being alone, often by choice, and can provide opportunities for self-reflection, relaxation, creativity, and personal growth. Some people are more introverted and gain energy from spending time alone. They might enjoy their own company, pursue solitary hobbies, or simply appreciate the tranquility and freedom that solitude can offer.
On the other hand, loneliness is a subjective feeling of isolation or disconnection from others, regardless of whether one is physically alone or in a crowd. It can be an emotionally painful experience. A person can feel lonely even when surrounded by other people, particularly if they feel they can't be their authentic selves or connect on a deeper level.
So, a person can certainly enjoy being alone—valuing the peace, quiet, and introspection it allows—while simultaneously disliking the feelings of isolation or disconnectedness associated with loneliness. It's also normal for these feelings to fluctuate based on one's circumstances, experiences, and mood.
If you or someone else is struggling with feelings of loneliness, it's important to seek support. This could involve reaching out to loved ones, joining clubs or groups with shared interests, or seeking professional help such as counseling or therapy.
