Here's a lil stressful method to wean yourself off Facebook. It's what I did.
Use the settings / notification tab to disable certain notification type. E.g.:
* Some one tagged you
* comments on a discussion you liked, commented...
* who viewed your page
* who shared a link....
Eventually, Facebook ignores some of these settings in a desperate attempt to bring you back.
So create email filters to delete Facebook notifications based on certain keywords.
Also use an extension to block those fun / addicting autoplaying videos.
1. Did not delete my account, an attempt to guard against someone impersonating me there.
2. Deleted all content I had stored there. Obviously I don't believe FB actually deleted it, but I figured their soft delete is as good as it will get.
3. Asked all FB friends to kindly ignore my account, not to tag me or post pictures of me, and that if they saw activity from my account they can be assured it was not from me.
It did not bother me at all not being on Facebook, and still does not. There seem to be no drawbacks whatsoever. When I read about people feeling that their lives would be ruined and that they have no social life without FB, I kind of just shake my head.
