Boot camp Boyfriend

So my boyfriend and I are both 17, he’s doing some deal with the army where he goes to boot camp this summer and then returns to complete his senior year of high school. Summer is coming up so quickly and I’m already stressing out so much about him being away. I know that him and I can get through it, it’s just that I’m so nervous about it. This man is my best friend and my rock. We talk every day, all day and he’s always there to talk to and being without him is gonna be so tough. Is there anything that any of you did to cope with this that have had boyfriends go to boot camp? Any advice would be greatly appreciated ❤️❤️
