I'm jokingly being serious. It's a thing I do.
I'm tired, too. We're allowed to take breaks though. I've taken several now. The best way is to just go. Announcing it doesn't work, it adds pressure. Even if you plan a vacation and promise your followers pictures when you get back, you'll be constantly working, looking for those shots, thinking about those things to say; not getting away.
Maybe I'm lucky, but my experience tells me I will not be forgotten or become irrelevant if I vanish. I'm good at going poof. If you decide to take a break, I'll notice and I'm sure others will as well. Don't worry about the worrywarts. All it takes is a simple heads-up comment. "I'm back." Myself and I'm sure many others will step up to ensure you can pick up where you left off.
