...I think I do.
It's when you have a fear of not having a mobile-phone. I experience this periodically and get down-right anxious and stressed-out if I've left my cell phone and/or I can't access it...I know, it's ridiculous! It's become a digital addiction and oddly enough, instills comfort when I have it.
Oh no, what if they put this in the "Diagnostic and Statistical Manual of Mental Disorders"?!? Will it be code #911?
