I've been Facebook free for several years now. It feels great, and I didn't have to cut anyone out of my life to do it (who I wasn't otherwise already communicating with). Much less noice, more productive, both in my life and in my relationships.
You should quit when you write up a post like this and submit it to HN.
Go take a well deserved break to find yourself. Meditate, or do activities that you feel are meditative.
If you need a place to stay and rest, look to your friends/family.
If you have a business that needs to be taken care of, either sell it or hire someone to take over things like customer support, etc.
If you're feeling burnt out it means you need to take several months off because you haven't been taking care of yourself or doing the things that energize you.
I wish you the best of luck.
