Okay, I have to interject here.
@JEKBreatheandBelieve I mean no offense by this at all. It isn't about remembering something positive. It is about feeling it. Getting all of the senses involved, or if that is not part of the trigger, finding the sense and annihilating it with a positive feeling. The key word is feeling. Here is my experience.
I used to almost drive off the road when I saw a Back Rack (installed on the back of trucks to secure goods carried in the truck). I won't get deeply into why. It was seriously impairing my ability to drive and I needed to drive desperately to get help from T's etc. I was desperate. I remember the moment. I was sitting behind a truck at a red light (even know the intersection). It had a back rack and I was seriously melting down in my car. My brain went ballistic looking for a way to stop myself from reacting. It suddenly came to me that I needed to figure out a way to change how that backrack made me feel. I needed to feel powerful when I saw it. Had to.
How the hell did love or safety fall into that object that kept triggering the hell out of me? How do I get a powerful feeling out of it? It suddenly occurred to me that I needed to see that backrack driving down the driveway - leaving - because I wouldn't back down. He left first. Always. He would come, try to completely terrorize me and I would stand my ground and he would leave. Powerful. Yes, I had power. Yes, in the end I melted when he left but I made him leave. Finally I decided I had to leave that situation. I left him and that freakin backrack behind. I tapped into the strength and the courage that it took to do so. To walk away from everything I cared about. I let that feeling course all through my body. That was a conscious choice. I had to allow myself to feel powerful.
It isn't about thinking good thoughts. It is about allowing yourself to feel them. Through every cell in your body. For a while afterwards I would have to force that feeling to take over my melting down when I saw a backrack but it left me - the feeling of powerlessness left me because I forced an image of me being brave and strong and fighting for my freedom and winning that.
It can be done. I have used it over and over again and my life has changed tremendously. Honestly, this is a really important posting. This is a really valid and powerful question. It changed my life when I realized that I could overlay one set of emotions for another.
