Forgive me if this is somewhat subjective and feel free to close if it's too broad.
I've been a freelance designer for a bit more than a decade. I work from home. I don't really have any complaints in terms of the projects, work, money, clients, hours, etc. Well, no more complaints than would be considered standard in the course of a week.
However, I find myself terribly isolated and not necessarily by choice.
A bit of background for clarity:
I am single, never married, no children, and no immediate family. In fact, only distant family across the country I haven't really seen in 25 years or more.
I'm not a drinker. Therefore I tend not to venture out to pubs, bars, or parties.
I'm a steadfast atheist so church or religious gatherings are best avoided, otherwise I simply anger people.
I don't feel anything on the internet - Facebook, Twitter, Instagram, discussion forums, SE - is really socializing. Ultimately you're still by yourself typing. In addition, simply repeating what I do for a living is not a break from work.
I know people, well, I know a few couples. But couples don't tend to hang out or socialize much with non-couples. And, while I do take opportunities when they are presented, being the third-wheel can become stale in itself.
Customarily, I would meet friends at work or school, neither of which have applied for many years.
I thought about taking classes at the local community college or something but do I really want to pay for a class in a subject I could not possibly care less about just to socialize? The local schools offer literally nothing of interest (smaller city without a great deal of diversity).
I'm not lonely, just always alone. I think my work could only improve by being exposed to more social aspects in life.
I find myself always working because I have the time. This has been good for business but not necessarily good for attitude at times.
So, working from home, alone, how does one combat the inevitable isolation which arises?
