Does going out ever get easier?

For context, I’m an almost 20 year old girl living in a big city. Everyone around me seems to love going out and socializing, and I cannot recall a single point in time of my life during which I’ve felt the same. I’ve been in therapy, I’ve been on anti anxiety medication, none of it has worked. The transition from home to the outside world is so incredibly difficult. Sometimes, when I am inevitably forced to go out, I enjoy myself. But that doesn’t change how I feel about it at all. I hate going out, I hate socializing, I hate being called selfish because I don’t want to do either. Does it ever get easier?
