Loneliness and solitude is found in one's core, and those that surrounds us all.
When you awake early, before the dawn, or have been unable to sleep through the night like most mortals, you sometimes understand night better than any, and come to an agreement with solitude, loneliness.
It's not a sickness, it's not always a negative. It varies. Most would associate loneliness with an anti social person, one that can't get along with others.
Everyone's a bit of a loner, everyone's a bit of melancholy. We are all left to despair and mourn.
The question is, how you deal with loneliness, solitude.
It's good to be alone, where you can have quiet time, peace of mind, listen to yourself, and allow yourself to take a step away, a second's hesitation. After all we're human. We're born alone, and we die alone ultimately. Coping with loneliness is easier than thought. Not requiring someone's assistance, not needing others to be happy is true independence. To deal with life, without the consoling of another. True independence. You surround yourself around people you truly want to be around, those you truly adore and admire. Those you have a true connection with, not whom you need in order to make it through life.
That in itself is freedom, liberty, and independence.
