I've found the only permanent solution to my "Triggers/fears" is talking about them and talking about them until I find what it is they signify to me. Eventually I become desensitized to things and one day I realize that my reaction to past "triggers" has changed, my reaction becomes more normal to the situation, ie, yes the loud voices are a nuisance because I can't concentrate on what I'm doing, but they no longer mean more than that. Its a slow process of taking something apart, finding what it means to me and then putting it in its place.
