I also found that spending more time on Facebook made me focus on the wrong things in life. I spent a lot of time thinking about what photos I wanted to post to garner interest (in reality few look or care about them). I spent a lot of time checking in on people that I haven't talked to in years, which satisfies my interest without actually ever communicating with them. It just became sort of depressing after a while. It's low effort to become friends with someone on Facebook, and I don't think its healthy to be constantly reminded of these connections you've made in life through various events and never actively continue in real life. You just spend a lot of time thinking about the past or what could have been. I was expending so much energy and getting back nothing but fleeting dopamine hits.
I truly believe I'm better off without it, despite the difficulty coordinating events with people and being invited to things. I communicate more with people in real life now. I find I am more motivated to text or call people to check in. I also use other communication services more because I'm not satisfying my social needs through passive consumption anymore.
