A lot of people however do not realize that there is a huge difference between being alone and being lonely. I will quote something that is succinct for both.

But in the loneliest wilderness happeneth the second metamorphosis: here the spirit becometh a lion: freedom will it capture and lordship in its own wilderness.

The individual has always had to struggle to keep from being overwhelmed by the tribe. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself. But if one man runs to his neighbor because he is looking for himself, and another because he wants to loose himself. Your bad love of yourselves makes solitude a prison for you.
