I know the title of the article sounds negative and antisocial, but I actually do love the times when I'm alone. In fact being alone can be healthy and beneficial, it's basically solitude.
Solitude provides many health benefits such as stress reduction, boost in creativity, connecting with spirituality, and even renewing your energy!
When I'm alone I feel completely free. I live with my parents right now so I rarely get time for solitude, but when I'm alone in the house I act however I want which eases my brain and reduces stress.
If you're someone who rarely gets time to be alone I bet you can relate to this article, and if you're lonely remember solitude because it might actually give you a more positive perspective.
Likewise I like to be alone sometimes, because that is the time I inspire myself and brainstorm on the way forward.
