How do you deal with your crush who is two years older than you graduating from high-school?

He'is in year twelve and im in year ten, and i do taekwondo with him also outside of school. its gonna be kinda sad :( coz i know his timetable and im so used to seeing him in corridors etc. oh well his twin sisters are in my year, and im good friends with them and our parents know each other so its not like i wont really see him or hear about him, but still
