Your post seems to insinuate that being rich means you can't have problems, which I'd disagree with.
I also think it's kind of disheartening to hear a mental health profession scoff at someone who is admitting that they're struggling.
I'm a therapist and have plenty of clients with high profile jobs that want to give up. We're all human.
I get your frustration though. I'm frustrated too. But Mcvay is human. I commend him for deciding to step down if that's what's best instead of taking the paycheck and half assing it.
