One of the reasons I started reading self-help books was because of my extreme anxiety. I'd lived with it for years, and couldn't take it anymore. And while I will happily report that I have made great strides regarding said anxiety, due in part to all the aforementioned self-help books, combined with therapy, one of the things I still haven't "recovered" from is my anxiety surrounding my smartphone. I have had this phone-anxiety for as many years as I've had anxiety, but on all the worst ends of it, and yes, I still have it even now. Sometimes my phone anxiety gets so bad I leave it on airplane mode for days. And I've tried to explain it to my hubby for as many years as I've felt this way, but he has never understood.Nor really did I until I read this book, and now ALL of it makes perfect sense. First of all, I got it because I was convinced it would tell me I'm not addicted to my phone, and while that is mostly true, it became glaringly apparent that I still have nervous tics surrounding my phone. And second of all, I got it hoping it would shed some light on why so much of my intense anxiety surrounds my phone, but it did far more than that. "Shed some light" is an understatement, and I found the lengths that people go through to make phones addictive to be disturbing and shocking to put it mildly.For instance, did you know that apps are carefully designed to give you a rush of endorphins at the exact right moment, to keep you from closing out of them, carefully leading you on for hours at a time? Because I certainly didn't. I don't mean it's a side-effect of an app. I mean that they design them that way.And as for all the anxiety I've had surrounding my phone, I finally have my answers. I'm not crazy. It wasn't in my head that my phone made all my anxieties worse, specifically my frazzled emotions, and inability to feel calm. But if there was any one thing that shocked me the most while reading this book, it was the realization that even I, who still to this day puts my phone into airplane mode, has a mild smartphone addiction. Even I do. And if that is possible, considering how strong my aversion is sometimes to my phone, then what in the world are these phones doing to others?Nothing good, I'll tell you that much. This book was an incredible find for me, and I'd recommend it to literally everyone in the world who owns a smartphone.
