Hi waterknob, I'm imagining "miserable" is a big understatement, right??
And it's not surprising you made a mistake when you're so emotionally and physically drained, but well done you on standing up for yourself, is there any possibility you could carry that on and push for less hours?? At least some less hours??
It's not really disputable that most people working that many hours aren't going to be "working their best".........and in your line of work. Hope you're still keeping the option open not to stay though, got to put yourself, and your mental well-being above a job at times.
And your self-esteem being kicked to the curb............hope you're not forgetting how much we really value and appreciate you on here!!!
