Luckily it is easier to stay in touch with people, no matter the distance, today than it was 20 years ago when I was a teen. Today you have cell phones that don't charge you to call long distance. You have social media such as Facebook, Twitter, Snap chat, & others. True it's not the same as being in person but it is a lot better than "I guess we'll never talk again."
Hang in there. You can get through this.
