Pretty sure I have this disorder

A recent article in the Evening Standard introduced a "new, peculiarly 21st century affliction" called nomophobia or "no mobile phobia," which is exactly what it sounds like - the fear of being out of mobile phone contact. Besides citing research that claims up to 53% of mobile phone users feel great anxiety when their phones run out of battery life or have no network coverage, the article also suggests ways to avoid nomophobia, such as carrying a charger at all times or remembering your most important phone numbers.
