I have little in the way of pysical fears, but I have a irrationally intense fear of both anger and hatered. I have found that a person cannot think rationally when angered and often tends to act impulsively. Thus, I fear both being overcome by anger (I dread not being able to think coherently), and I fear the anger of others (I could never know what they would do I such a state.) Perhaps this came around when I was almost severely hurt by an angered person. Hate works much the same way.
