You know already that your phobia is irrational. This however does not help as phobias are controlled not by our conscious but by our subconscious mind.
Phobias are usually based on some significant emotional event from our formative years. As an adult, anything which reminds our subconscious of this event will trigger the response you are familiar with. That's right, the fear, the anxiety, the panic.
First Choice Hypnotherapy uses a combination of Cognitive Hypnotherapy and Neuro Linguistic Programming (NLP) to enable people to overcome their phobia. Most simple phobias can be overcome in one or two sessions.
