When you decide to go dark, do you tell people before you do?

I've turned off my phone for a bit over a week now.

I've switched SIMs and nobody knows my current number.
I've logged out of all of my socials without a peep.

Only communication I've had is some worried emails from my father and my girlfriend and I told them to leave me alone.

I can't imagine if anyone else cared to message me on my socials since I haven't deactivated them yet, only people who know I'm in this dark place is my parents and my girlfriend.
