Social Media “Friends”

So I’ve definitely cut down on the amount of friends/followers on my social media pages since having kids but still feel like I have a good chunk I don’t talk to but was friends with in grammar school or high school… can someone help me be more ruthless and finally just defriend those people? Why am I giving them access to my personal life and family pictures? They don’t “like” any of my posts and many of us haven’t talked in over 14+ years. Why do I feel weird about cutting those ties? 😑
