18, new swimmer

Hey all, I learned how to swim from scratch during my senior year in high school with no intentions to compete - just wanted to learn. I ended up loving it, and I picked it up fairly well, so I swam summer league the following summer. I loved competing and getting better, despite my lack of experience. Now that I'm 18, I'm pretty devastated now that I did not start earlier, or get the chance to swim varsity for my school. I love love loveeee breaststroke (: With less than a year of swimming and about 2 months of working on ***, I swam a :49 for the girl's 50m *** during that summer. I know that this is not the best time in the world, but for the amount of time that I'd been swimming, I'm really happy with myself. I found my sport kind of late you could say. Now I'm a freshman in college and debating if I should join masters. I'm not sure how the program works. And I loved the camaraderie of swimming as well, and I'm not sure if many people my age swim masters and if I would feel out of place. If any one has input, I would greatly appreciate it. (:
