You are absolutely right. People are a lot less loyal and much more fickle so we tend to lose more friends than we can even make and we push people away after they've made one mistake without looking inward at our imperfect selves. I currently have found teens of be friends that have actually become "real" friends. We hang out, have dinner, sleep over, and play all the time. It's like i stepped into an alternate universe. The one thing that i can say worked was changing my perspective of who i thought I'd be good friends with and just allowed myself to be vulnerable. I hope that works for you. Everyone needs a good group of friends like i am fortunate have.
