There are many different ways to approach healing PTSD, but one of the commonalities about many of these different approaches is that they focus on the not just the mind, but also the body. The Pesso Boyden System Psychomotor (PBSP) approach is yet another one of them that does this. PBSP was created by Albert Pesso and Diane Boyden, two people who were professional dancers. They noticed that when they asked their dancers to try to express their emotions through physical movements, the dancers felt much better and relieved afterward.
Maybe we just have to let all of our emotions out of our system after all. The mind and body are more closely related than most of us realize, and there are many different ways to get your emotions out. Some of us feel better after simply talking or writing them out. Others might get relief from going for a run, punching a bag, doing yoga, or dancing around a room.
Sometimes though, none of that is good enough, and you might actually need to act out the scenario that is bothering you. The theory behind this approach is that the reason your memories keep haunting you is that you were never able to see the result or end. So what PBSP does is gives you an outlet where you can reenact all the potential scenarios of that past memory in a group acting setting. This can hopefully allow you to make peace with your traumatic experience and be able to move on from it.
Dancing and acting might not be able to solve all of your problems, but it can be a good mood booster and a fun place to start.
