Screens and phones provide a personal disconnetion which allows for rudeness and general asshole behavior, sadly. A sign of the times! :( My heart goes out to you, Rachella! At least you learned some new things about your limits and that is good & positive, even if the rest was crap. Nobody should have to put up with jobs they despise, and I say this from experience.
I recently changed my career (as restaurante manager) which had made me crack, much like you.
Now, though I am poor, and living off freelance writing as my new writing career grows, I have never been happier! Shoulder on, Soldier Rachella! you will find your comfy corner again, transitions can be bumpy!
