Loneliness is the absence of desired contact by someone or something else. The something else has to be explained. I'm thinking of somethin like an amusing pet, like a puppy. Puppies are great companions who ask for nothing more than to be in your company.
Everything depends on what you want. If you want to be alone to think or feel, that's not loneliness. If you are left alone when you desparately need someone, that is lonleliness
