As much as you don't want to hear it, it sounds like you're in a comfort zone. You're comfortable with where you are now and don't want to change anything but at the same time you have a lot of underlying stress and anxiety about your future and social life. There's nothing wrong with your position in life right now as long as you're happy but if you want to change do something way outside of your comfort zone to break the cycle. For example find a random club in your university and join it. Eventually you might find your passion or drive and find yourself. Have you ever thought about trying to manifest and channel some of your fantasies or imaginations into the real world? It could provide a bridge of some sort, idk just a thought.
