Darling, that was just creepy.
a persistent, irrational fear of a specific object, activity, or situation that leads to a compelling desire to avoid it.
(psychiatry) an abnormal intense and irrational fear of a given situation, organism, or object
A phobia isn’t something to be taken lightly- M.O.D. actually dislikes how often the word is thrown around. A phobia is a great, IRRATIONAL fear. People will go to great lengths and even put themselves in DANGER to avoid the thing they are scared of. In the event they cannot avoid it, they will be marked with distress, anxiety attacks and severe hampering to social skills.
So… In short, no, that doesn’t sound like a phobia. Your reaction, although extreme, was completely rational.
