Ive found... a completely different way. Im reluctant to talk about this and reccomend it to people because, at first glance, it would seem like the worst idea imaginable. But its actaully great.
I scare the crap out of myself on purpose. Scary stories and the like. I do it over and over and over again. It gives me... a focus. something scary to put my fears onto, but that I know will have a finite duration, and can be stopped at any time. I wish I'd figured this out sooner.
I spent so much time trying to avoid fear, that it overwhelmed me when it came. I knew I had to expose myself to it again, until I became familiar with those dread feelings again. Too much time hiding from fear. I'd get it in my head that i was afraid of one thing or another, but no. I was just afraid. Conquering one thing was meaningless, since another would take its place.
I wish I'd figured this out years ago. So just incase you're curious, and I really think you should give it a try (because why not? It may just work.), here's a story about Gristers: https://www.youtube.com/watch?v=FztuiSqZPMg
