@AzulOscuro Yeah, I think perhaps I could take a step back when faced with technology-challenges and do something else. That way I could do something positive and over which I have some control.

That's fascinating @MaverickLovesYou... I think that's what happened in my case. There's a David Hanscom video on YouTube where he says anger and anxiety are on the same continuum, but your explanation about the adrenaline is a key point. Thank you....

I wonder whether it's possible to figure out how to get rid of that excess adrenaline?? Maybe through exercise?
