Building up a social circle
TLDR: How can I build more of a social circle?
Just looking for some advice on what I can do to build an actual social circle.
I'm 22M and haven't had any formal education since secondary school. Always wanted to go to university mostly for the social side but couldn't afford it.
My life consists of work as of late. I only really have 1 friend left from secondary school and we don't talk often. The rest of my circle are work. My only social circle is people I work with, and then occasionally seeing them outside of work with organised events. They've introduced me to their friends and often talk about meeting mine, and that in itself is a reminder that I don't really have anyone. The people I get along with at work are moving into other roles too so I see them less.
I just want a social circle which is more than just my work, and I don't know where to start. I.e today I had plans with someone from work, they cancelled due to other reasons but now I find myself at home, with no clue what to do.
