Yes, it's described in detail on page 190 of the DSM-5 under the heading "Separation Anxiety Disorder" (309.21 / F93.0). Here's a quote from that section:
Quote:
Individuals with separation anxiety disorder ... experience recurrent excessive distress when separation from home or major attachment figures is anticipated or occurs (Criterion Al). They worry about the well-being or death of attachment figures, particularly when separated from them, and they need to know the whereabouts of their attachment figures and want to stay in touch with them (Criterion A2). They also worry about untoward events to themselves, such as getting lost, being kidnapped, or having an accident, that would keep them from ever being reunited with their major attachment figure (Criterion A3).
...
Depending on their age, individuals may have fears of animals, monsters, the dark, muggers, burglars, kidnappers, car accidents, plane travel, and other situations that are perceived as presenting danger to the family or themselves.
...
Adults with the disorder are typically overconcemed about their offspring and spouses and experience marked discomfort when separated from them. They may also experience significant disruption in work or social experiences because of needing to continuously check on the whereabouts of a significant other.
...
individuals with anxiety disorders typically overestimate the danger in situations they fear or avoid
...
Most occur more frequently in females than in males (approximately 2:1 ratio).
Please note, I'm NOT saying that
you have Separation Anxiety Disorder. I'm saying it's a big problem where I live, but you don't live here. Perhaps it's hardly a problem at all where you live.
