I'm at peace with Facebook. I enjoy it, but some time ago I had to do some work to keep it that way:
- Unfollow everyone (no unfriend, just unfollow). This could take a while, but you can do it from the friends page.
- Disable non-essential email notifications
After this, your timeline will be empty. No distractions. If you want to see what's up with someone, you go to their page.
I also made a friend list with my close friends and my immediate family. That's what I open when I want to know what's up in my immediate circle (I have it bookmarked so I don't have to fish for it in the ever-changing FB UI).
