I know it seem wrong. I'm gonna explain it carefully. This "things" are the reflection of your fears/hates/bad feelings in general, that your subconscious throws at you due to your "problem". So you can't control them consciously, nor can you really damage them short-term. But in fact there's one way to win the battle against them. Stop fearing them, that easy. Of course they'll keep apearing, and short-term they can deal a lot of damage. But when they are gone, and they will allways have to temporarilly stop at least as long as you have medicines, they can only affect you as long as you let them affect you. So, by humiliating them you make theyr damage affect you only in short-term, but ineficient in long-term, and slowly, you drain their power (as long as you have medicines too, that's important) Of course they'll get angry/violent if they can see what you are doing, because in the end they are your subconsciousness trying to beat your consciousness, and the brain is the most powerfull of the muscles. But slowly, second by second, minute by minute, they'll start appearing less times, because if you combine medicines with the overcoming of the fear they create in you they just can do nothing. I know what I'm talking about, I studi biotechnology and a lot of my teachers come from the neurological institute near my university, so I ask them. Look, if you don't believe this just keep one thing in mind:
THEIR ONLY LONG-TERM WEAPON AGAINST YOU IS FEAR, DON'T LET THEM USE IT!
