How can I grow as a person?

I (22M) lack common social skills. I am an unattractive shy introvert, so I never had a girlfriend. Also when I talk to people who I am not very close to I am always very awkward and make things weird because I don’t know how to act or what to say. I am about to finish college and feel like I wasted most of my time because due to my social anxiety and awkwardness I don’t have many friends and missed out on a lot of things people my age do. This is having an extremely bad impact on my life and I need to change before I turn 30 without having friends and not knowing what being loved feels like. Are there any books, websites or youtube channels that can legitimately help you improve your social skills?
