Across, it's not only you! I'm nervous, too, and, FWIW, so is the most relaxed person I know: my mentor, who shrugged his shoulders and called it 'only a minor glitch in the system' when, as a new graduate trainee, I made a stupid mistake that lost the firm 1.5 million. He's selling his stock holdings and buying commodities. He's not a conspiracy theorist, just a reasonable, extremely smart person senior enough to have been trained to spot the shot before it hits the fan.
I am actually reading Jonathan Freedland's book. Not my usual preferred style of fiction, it's a bit too airport-novelly for my normal tastes. But I started the first chapter and that opening scene where the insane president insists on launching nuclear attacks because NK said something that pisses him off just really hit home. I could envisage Trump doing that for the reasons book Trump POTUS does. It chilled me to the bone because, albeit fiction, it rings true.
Yes, I'm nervous. Not scared, not panicked, but nervous and acutely aware that there may be a 5% chance of this man being the reason I'll never see the other side of 40.
