@Wafflebff Hmm, advice? Well, I think since I posted that I've kinda come to peace with the fact that I'm growing up. (which was what I was struggling with) But I'd be happy to try and help!
So, the first thing I'd recommend is prayer. Religious or not, we could all use God's help, right?
If you're not very big on that, I guess the best advice I can give you is this:
If your best friend is a girl, and you guys have been great friends for at least a year, I'd say, just wait it out. The distance is temporary.
Now, in the case that doesn't happen, you WILL make new friends! OR new friends will make YOU! Wait, that didn't come out right. . . . . Anyway, you know what I mean. I'll pray for you, and I hope everything turns out okay! I don't go back to school until the 22nd, so I guess I have like 3 days left. I started the countdown at the beginning of August, though. Always gotta count down the days until you lose your freedom! ;P XD
