It's not too late to change that, you are young. Social life can take effort to get rolling, but once it does things can change pretty quickly and it becomes fun to look forward to hanging out with friends. There are a lot of people at meetups who mainly just want to meet other people. Most people have some area where they have something interesting to say about, just try to find that. Find a meetup that interests you. Talk a bit, find out someone likes to do something you enjoy or think would be fun (sports, museum, music event, etc) and ask them to do that activity with you sometime. Being positive and friendly helps people want to be around you.
