What I've found is no one skill is a cure all, but a mix of them will often net the best results. Talking to yourself and reassuring yourself like friend or ally works well. Replacing negative thoughts with positive "cognitive therapy", pushing your emotions away, looking at and analyzing emotions. And often the most effective course of action is focusing on conscious activities, which involve your senses or analytical thought "math, speech", etc. Honing these conscious skills can often reduce these corresponding negative effects. For instance honing you hearing skills to separate sounds "like instruments from your favorite song" can help avoid sounds that may confuse the subconscious, contributing to audio hallucinations.

I see this as guerrilla warfare, so I use every tactic, trick or cheat to my advantage.
