"Fear includes doubt, regret, jealousy, pain, suffering, or anything that leaves you feeling as though you “lack” something, that you require something that you don’t have in order to be who you truly want to be."

I like this way of defining fear. It actually tangentially fits with something I wrote. I covered the idea of "needing" a purpose and how that is sometimes exploited. I didn't touch on fear but the way you present it here works well with that. The idea of purpose or the lack there of, can be used to make people live in fear of not being what or doing what they are supposed to.

"Fear is not inherently bad, it is simply a distraction from our deepest desires."

I like that you acknowledge this. We often get this view of certain emotions an "negative" but they all serve a function. The problem, as you point out, is when they become a detraction from other things. It is fine to be afraid of a bus when it is coming right at you but that shouldn't stop us from riding it when we need to get somewhere, if you will forgive the poor analogy.
