Look into threat modelling, we're all striving for more privacy-friendly ways to keep in touch with people, and if you seal yourself off too early, you'll suffocate.
I know my friends and colleagues well in person, they know that I'm a privacy nut, and we agree to not report me missing just because I'm unreachable on a particular day. But knowing that they SMS each other their plans and that I'm probably not a target of the state, I'm cool texting them things like when we're eating out together.
Also don't be disheartened, I keep at it even though my methods are nowhere near airtight. Even if every move of mine is known, the surveillance capitalists will at least know that I am flipping them off and trying my best to make their jobs hard.
