Hi everyone just wanted some advice, I’m still Facebook friends with a group of people who I’m no longer in touch with and seeing anything any of them post is a real trigger for me and can send me into a real spin, so I have all of them on mute and hidden so I see nothing,  but should I cut all ties for good and delete all of them and risk being called petty for the mass unfriending or should I just leave it as is and work on not having such intense feelings over all of them ? 
Sorry for such a long winded post )it’s my first post here so I was nervous)
