I’m looking for a single word, kind of like loneliness, but without the negative/saddening meaning for describing the act of being alone but preferring it, doing it by a conscious choice.
Answer
The word you are looking for is reclusion. A person that makes this choice is a recluse.
EDIT: Reclusion can also mean forced solitary confinement. Seclusion also works. A synonym for recluse is hermit.
EDIT: Added links.
