It is becoming more common for people to say they have no close friends. This is a phenomenon that is largely attributed to are disjointed society and a symptom of the internet, social media, and cell phones.
These days, it's getting easier and easier to ignore the people around you. This makes it easier to live in your own microcosm and be isolated from others. It usually starts as a matter of convenience but can become a lifestyle.
I myself have no close friends. I am married, have a child on the way, but unfortunately my friends seemed to gradually disappear. I have no regrets though. I'm lucky to have a great life and am fulfilled.
However, I know that professionals will tell me that I need social connections. While I know there is truth to this, I believe I have a different disposition than other people. Instead of feeling bad about it, I have been able to thrive do to my friendless condition.
This is because I have many outlets. That's the key I think. If you have minimal or no friends you need to stay busy and have hobbies that occupy your time and are meaningful.
Don't get me wrong though, you will have bad days. You will long for friendships. However, if you are able to you can thrive without friends. If nothing else you can do this as a means to an end. Sometimes it's necessary to find a coping mechanism to help you through something. Friends are a coping mechanism, and without them you simply need to get more creative. That's what I've done, and so far it has worked.
