Well. There is 2 choices.
1. You keep being an introvert and try to find the good things in that. I`m an introvert too and I find it easy to concentrate on work, for example. Thats why I`m being way more productive and don`t waste my time on little chats with someone. There is tons of benefits in this behavior. Just google them
2. You try to get away from your comfort zone and interact with the society. And by that I mean REALLY get away from it. You will need to force yourself to talk to people, to have some public speeches and other stuff. In the beginning it will feel like hell, but later on you will feel yourself way more comfortable.
Its up to you to change your life dude
