omophobia
Short for "no-mobile-phone phobia," this is exactly what it sounds like: the fear of being without your cell. According to a study of 1,000 people in the U.K., 66% of the population fears losing or being without their phones at any given time. Some of the symptoms of nomophobia include anxiety or negative physical symptoms if you have lost or cannot use your cell phone, obsessively checking to make sure you have your phone with you, and constantly worrying about losing it somewhere. Interestingly, the study found that women suffer from this more than men.
If this sounds like you, experts suggest employing common anxiety-relieving relaxation techniques like yoga and deep breathing.
