Have you tried just sitting with that anxiety instead of fighting it the moment it shows up?
What you're describing is real, and it's not really about addiction in the classic sense - it's more that your nervous system has learned to rely on a specific tool for regulation. When that tool disappears, you're suddenly aware of everything your brain was quietly processing in the background. The anxiety spike is genuine, but here's the thing: it usually peaks and then starts to level out if you can tolerate it for a bit. The problem most people run into is they assume this means the detox isn't working, so they grab the phone again, which just teaches their system "yep, phone is the solution" all over again.
The real pitfall nobody mentions enough is that sitting in silence with racing thoughts feels *exponentially* worse than it actually is. Your mind will convince you that the anxiety is building toward something catastrophic, when usually it's just... noisy for a while and then quieter. It's not dangerous; it just sucks. If you want to keep trying the detox thing, the trick is building up tolerance slowly instead of going cold turkey. Put the phone away for 20 minutes, then do something that occupies a different part of your brain - walk outside, sketch, cook something. You're not white-knuckling through raw anxiety; you're just not using the phone as a distraction *and* you're not sitting alone with your thoughts either.
