Oh, congratulations on reaching the finish line! That's so awesome!
Truth be told, I have no idea how much I've written overall but I guess it's ... quite a bit?
My current main series is at roughly 1.6 million words (in the original version, the revised one has an additional volume and some added chapters so it's longer), the prequel has 250k so far and there's extras to the tune of another 140k. I have another series that's completely finished at about 440k (extras included) with a spin-off series that's another 240k so far but still in the making. Then there's a short story collection of around 75k, another at 49k (but still working on the last two stories), and 48k of assorted short stories. Then I have a couple of standalone novels, being 158k, 94k, 73k, 116k, and 105k (but with an extra pending halfway-finished) respectively. Also, another two series that I am currently writing, one at 416k (slowly closing in on the end there) and the other at 220k. Right now, I'm preparing the next one but I'm only 10k in there. For other projects, I only have some scenes here and there to get a feel for them but they're all for much later when my current stories and others I've planned are done so I'm not counting those.
I also have a second account that's at roughly 130k words right now but I haven't uploaded everything there yet. It shouldn't be much more though. The first novel was 63k, for the second one I'm only 16k in, and the rest are short stories and novellas that currently amount to about 78k. I do have some novels and series lying around under the same name that I wrote some years ago but I still need to translate those to English and brush up on them since they're, well, old. Everything else on either account is from spring 2018 or later so relatively recent and there difference is pretty stark and I wouldn't dare publish them like that. I guess those old ones would come up to a couple hundred k words or maybe a million though?
