He’s leaving

One of my very close friend is leaving to basic training on August 12 the days are coming up so fast. He’s my go go person, someone who I tell things and he’s always there for me as I’m always there for him. I’m going to miss him so much and I’m so scared, I don’t want him to leave, but there’s no choice! He’s someone I truly love and appreciate so much. I don’t know what I would do without him. His contract is for 3 years. How do I cope with this. We always FaceTime and especially at night and we fall asleep that’s something I’m going to truly miss. I don’t know how to cope with everything I’m just to sad 😞
