As someone who experiences unusually high amounts of fear, I've tried all the normal "tricks" to handle fear, laughter, facing it, seeking support, etc. When those failed, a few unconventional tricks such as imagery and metaphors also proved useless.
Fear is fear, you can't hide it or run away from it. You can't use tricks to cover it up. You can only experience it, and take what you can from the experience. It's learning how to cope with the fear that must be overcome, not getting rid of the fear. Over time I've begun to realise it's not as negative as it's made out to be, it's possible to experience it without getting physically poorly from it, and it's all to do with coping. It can be a positive experience as long as you don't let it make you ill.
