A. Yes, it may be considered a phobia, or more specifically situational type phobia. However, the important thing is whether is this fear reasonable? Do you think it's out of proportion? Phobia is a fear that one perceive as irrational and out of proportion and yet one feels and is affected adversely by it. If this fear is appropriate (e.g. fear of falling in mountain climbing) it's not a phobia.
