I'd say it depends on how you are/feel when you're alone. Energetic? Alive, curious, full of plans? Never bored, excited by the possibilities of life? Do you enjoy being with yourself? Never scare yourself with your own thoughts?

If the answer to all these is positive, then alone is healthy.

But if being alone ever leaves you wondering why you're alive, or crying non-stop, or drinking till you pass out ... being alone is a danger sign. It's not good for you.

I'm a hermit, a cavedweller. I love my cave, and I think it's good for me--I'm happy here. No, not happy ... I don't have to deal with people, and that makes me content. But not healthy. So I have a job. I have a job because it's necessary for my mental health. It forces me out, among people, and not just my friends.

You probably know deep, deep down what you need to be healthy--but it may not be what makes you comfortable.

My opinion.
