I have good amount of confidence and social skills but yet still lack a social life and have no friends. How can I build a social circle from scratch?

I never really had social anxiety, shyness or timid behaviour unless maybe I was completely new a social environment or when I was younger. I would say my social skills and confidence are decent and average. But yet I still lack many friends, people just believed I was weird I suppose. I lost my one and only social circle a few months ago, over a silly confrontation. They treated me like a punching bag anyway, What can I do to build a social circle from scratch?
