How do I handle this??

Hi! I don’t typically come on Reddit for literally anything, but my boyfriend just enlisted in the national guard on Friday, his date to leave for basics is June 2nd. We both graduate high school sometime in the middle of May and I’m unsure on how I’m going to be able to handle it. He’s gonna be off at basics and I’m gonna be at college and I’m so worried about things that could possibly happen. I don’t know if we’re gonna be able to talk, I don’t know when I’ll be able to see him, I love him more than anything and I’m just scared that this distance is gonna end up doing something to us. Is there any advice any more experienced people may have that could help me? He’s gonna be gone for both of our birthdays and some holidays and I just wanna know how I can get through it without losing my mind or interest in him cause I’m terrified of that happening. I truly do love him and I want to make this last for a long time I’m just not sure about how to. Please help me :,3
