Why do we keep up with old friends on social media sites?

I’m thinking of quitting Facebook and just ready for a new real chapter in my life. I can’t believe it’s actually haunting me (to keep it or not)

What I do like about it is the easy contact through messages with artists, people I meet in college and stuff like that. I really have no other business on it and feel it a bit weird to add friends from the past. As if I have had meaningful discussions with them. Why do I feel like purging? Am I elitist? Is this natural? I feel like I’m being a hard ass for no good reason. I feel like nothing is intimate anymore. Facebook culture is purely look what I’m doing at this moment. I feel like it’s hanging with the mob, the popular people in high school all over again, and I purged from them too, even though I didn’t hate them. What is this overall feeling of being indifferent? My wife calls me a hermit already. Should I view life differently? I can never let go of blogging as it’s like a diary of my life on the computer. But I’m honestly just not feeling up to following others around. It’s kind of sad to say that I don’t want to follow certain people anymore. How can I justify unfollowing or unfriending. This is so ridiculous but this is what it has come to for me.

A bit about me.
Used to love journalism, I keep up to par with the currents, I love sports, I fancy myself a musician & artist, haven’t really written or recorded for almost a year now. Current college student, married soon to be father, need a job real bad. As you can tell I’m just trying to refine my life and tidy up the social medias. Got any similar struggles? I think the anxiety is catching up to me.
