How can you make genuine friends in an age where communication isn't valued as much?

I've went through the majority of my nineteen years on Earth feeling alone. I've never been able to relate to my peers in school, as I've always been the "old soul" type. My appreciation for "old fashioned" thinking has made me value communication skills and genuine relationships... in an age of "love reacts" and needless abbreviations. I'm not sure if the issue is that I don't have friends, or if my definition of "friend" doesn't conform to the modern standard. To me, a friend is someone who I can speak honestly with, spend time with, and trust. As it is right now, there aren't many people I believe I could have heartfelt conversations with or spend the day with - let alone trust. And yet, it seems that all most people want is someone to like their Instagram photos.
I really would like to have more friends, it would make the excessively long days a little more bearable. I mean, I don't mind binge-watching the Office between classes, but hanging out with actual people would be nice too, haha.

What are your thoughts on modern day relationships? How would you define "friend?"
