Word count was a method we used to tell the difference in what kind of story we were reading.
Short-Story. 20k
Novella. 50k
Novel. 75k+
etc.
80k+ is absolutely a marvel to behold, and you should be hella proud of yourself. I am proud of you!
Don't sweat the small stuff. Really. I've been working on my baby of a series for years now. I've given up counting, because I know a lot will not get used, BUT were useful in that I learned more about my characters.
I think that series is getting into 500k territory, and countless hours researching and planning. One day, I will have enough of it to get it out there properly, but until then, I'll keep leering over my cauldron stirring.

Also, if I may, can we all agree to stop apologizing for life and beating ourselves up for not devoting all our sanity and blood to writing? You're writers. Whether you wrote today or not. You do not have to pay tax to be a writer. You are. <3 <3
