Hi Lost, and welcome to the forum. It's not easy to reach out for help or think about living without alcohol, so congratulations for having the courage to want to change! Your life will be infinitely better if you don't follow the path of destruction that alcohol takes us down.
There really are other people your age that don't drink (or just have one or two, unlike us), so be patient and give yourself some time to adjust to living sober. Glad you're here!
