I've been afraid of a lot of stuff. Anyone that tells you that they are fearless are lying to you. Courage isn't the absence of fear. Courage is not letting your fears dictate to you how you are going to live.
This might not be too helpful. I know that phobias are irrational fears not controlled by the conscious mind and merely thinking about facing those fears can create sever reactions. You don't chose to have those reactions its a subconscious whammy. What you need is a way to make your subconscious feel safe. A Shaman would make you a fetish, a Magickian would give you a talisman, and a Witch would give you a charm but outside of any Magick their real power would be your belief in them.
Perhaps you have something in your life that makes you feel safe. Maybe it is your Trek. Find your talisman. Don't think of it as a crutch. Think of it as a life saver.
