Bless you, it’s completely understandable that you’re terrified. I think overthinking is a completely normal response, I don’t see how you can’t go through everything in your head!
I’m keeping busy too & trying to take my mind off it as much as possible but it just keeps coming back to me.
Just my husband & 3 of my work colleagues know. My colleagues are also extremely good friends, we are a very tight knit group & we talk about everything so they’ve been a huge support & it really does help to be able to talk to them about it. I feel awful keeping it from my sons & parents but I don’t want them worrying especially if there’s nothing to worry about.
Best of luck to you for Monday xx
