Leaving for the Navy

So today is the day my boyfriend leaves for bootcamp after today I won't see him for two years pretty much, I've been crying my eyes out all night, I'm proud of him but it's going to be hard being alone after 3 years of having someone be there for me through hard times. Any navy wives or girlfriends that can give me a bit of advice? How did you keep your mind off things while your s.o was away
