Unhappy?
Oh, noooo, wouldn't want to be 'unhappy' now, would I?
Angry?
A little too late to ask that, don't you think?
Fed-up?
Spot on.
Why?
Ask yourselves. You should know the best.

Normally, I would be 'yelling' about what I've given up on but it's over for me. No point yelling about it. I've given up trying to be nice. I've given up trying to 'treat you nicely'. I've given up trying to be patient. I've given up tolerating your lack of respect.
I've just given up and that's that.
