HELP!! I need some advice

ok so I'm a sophomore and my boy is a senior. we've been friends ever since the first day of my freshman year. I've never gone to high school without him. he keeps me sane tbh. hes moving about an hour to an hour and a half away, and I'm terrified. I'm so used to seeing him everyday and hanging out with him and his family on weekends that idk what I'm going to do with myself. I mean we have a scedule during the week when we hangout and he plays football and I cheer so we hang out friday nights as post game tradition and then saturday I'll usually go to his house after I get what I need to get done done, but in 6 months that's all going to change. I mean yes we have a plan for when he leaves, like how we expect things to go but I'm still terrified. does anyone have any advice??
