Go on.... deactivate
I always found it stressful when I posted a joke, reply or viewpoint on Facebook, as I was acutely aware of my differing audience ..i.e. 'friends'.
I knew whilst some people would find my joke funny or would agree with my viewpoint, there would undoubtedly be some friends who would disagree, misinterpret or simply take offense.
I would lie in bed at night feeling anxious thinking.... dam, I have upset so-and-so with that post.
I deactivated Facebook about three months ago and now feel happier, free'er, and definitely sleep better.
