“A phobia is an intense fear of something that, in reality, poses little or no actual danger”.
“Fear is an adaptive human response. It serves a protective purpose, activating the automatic “fight-or-flight” response.
If you have a phobia, you probably realize that your fear is unreasonable, yet you still can’t control your feelings. Just thinking about the feared object or situation may make you anxious. And when you’re actually exposed to the thing you fear, the terror is automatic and overwhelming.
