You need to find a community separate from your current social circles. That community will eventually lead to friends and connections. Find a group experience that has regular returning attendance. A gym class (not free weights, you need something where people are experiencing it together and talking during that time), church, a community college course, etc. This will get you interacting again. Be curious about people but not pushy about it.
