Can you teach yourself lacrosse?

I'm a girl and 15. I've never really done any sport in my life but I do run at least an hour 5 days a week and I'm really interested in girls lacrosse but there are no camps or programs available to me right now. Can I teach myself? What sort of stick should I get? I'm willing to give it my all and I might want to try out for my school team next spring. I'm going into 10th grade and I sorta feel like I'm at a disadvantage to all the other girls because they all have been playing since they were really young so do you think its too late for me?
