Congratulations
@BeanCounter ! I think it's perfectly natural to get emotional. It's a big change and a lot to process all at once. Sounds like it went very well though, and hopefully you can have a nice glide path out, if that's what you want.
I am another one who is anxious about actually pulling the plug. I think I've already mentally postponed from January (when DS starts full time nursery) to Easter 2021. A mix of factors: partly because of covid (DS may well not actually be at nursery much then or in the run up, and my big work project is now likely to last at least into January and possibly February 2021), partly because (due to Covid) it seems unreasonable to put my nanny out of work in January (especially as I know she'd like to take a break and go travelling before the next job: which I'm hoping would be possible by Easter next year, but not sure about middle of winter). But I'm sure there is some OMYitis in there too.
Funnily financial issues seem very far down my mental concerns about retirement. Which I guess is reasonable given my stash. But again I wouldn't rule out that those concerns pop up to bite me when I actually get there.
I have now joined the 2021 retirement thread though, so hoping that (and this one, and my journal) will be full of people helping keep me to timetable! I really am jaded now, and not doing my best work. Adrenaline, duty and occasional interest spur me on to "good enough" most of the time, but it's no way to live long term. Time to move on!
