How do you make friends? I have no friends other than my SO and it has been that way for many years. Even for online friends I have trouble knowing when to message, what to say, and how often to start conversations. I usually convince myself they don't like to hear from and stop initiating conversations :(
Chances are you can find a cause in your community people have gathered around.
Sometimes though you might be in aplace where there's just no community for you which is a reality in various rural areas. You might need to make the drive those 3 counties over.
If it's real bad you might need to decide between your roots and living closer to communities you mesh well with. Depends on what's important for you in life and where you can find work.
