How do i find out what is the phobia name for being abandoned?

Not a phobia..: Although it is not an official phobia, the fear of abandonment is arguably one of the most common and most damaging 'phobias' of all. People with the fear of abandonment may tend to display compulsive behaviors and thought patterns that sabotage their relationships, ultimately leading to the dreaded abandonment. This fear can be devastating, but understanding it is the first step toward resolution.

Abandoned: The closest ones Iam aware of are monophobia or autophobia. Neither deal exactly with abandonment.
