When I have gotten into a dissociated state during therapy my therapist will offer me sour candy to bring me back. It does work. Anything with the senses. A few weeks ago I got caught out and couldn't get back in. I panicked and called my therapist she told me to get ice and hold it in my hands until I felt better. It worked. For years I used to punch walls and doors to break out of a very negative and aggressive mood. I didn't understand it than but I do now. When I would punch the wall my hand would feel like I broke it. I would feel relief from the mood but I never put it together. Punching walls and doors caused me great pain that I live with today. Self injury is not the answer. Now that I understand what I was trying to do by punching the wall I have stopped doing it. I have stopped hurting myself. I realize now that I am just trying to switch. So now I will get sour candy or bitter food and it has the same affect without hurting me.
