How do you guys deal with living alone?

If I haven’t socialized in a while, loneliness kicks in and I suddenly start panicking. Like omg what are you doing. I remember I used to have a lot of friends in college but that was also because I lived in a dorm with other roommates and I was carefree being so young. I just want to be carefree like I was in my early twenties. Sorry for venting.
