I'm going to copy paste a comment I made a while back that I still stand by:
"""
I [deactivated Facebook for] three years and regret it. I realize now that I should have just shaped my use to fit my needs: unfriend or unfollow people I don't care to follow, write more messages rather than scrolling through the newsfeed, and join events and groups more deliberately.
Now I actually use it to keep in touch with people I care about, rather than just pretend that's what I'm doing.
I missed out on some things during my three years with Facebook off, and although I learned so much from having done it, I wouldn't do it again.
