I built an extension [1] that might be helpful to you. It blocks only the Facebook news feed but still allows you to use Facebook normally otherwise. I found the news feed was always the thing that drew me in mindlessly - I'd go on there to send someone a message and end up just scrolling for hours.
I don't believe Facebook is on a path that will end well for itself. Anecdotally it seems there's an increasing number of people like yourself who are fed up with Facebook and looking to dump it.
