It does!

If you need help getting stable, there is a place in Kansas City, Two Rivers, that has a special wing for trauma survivors. You don't interact with e rest of the psych patients at all, and they teach you about dissociation and how to manage it. They only take voluntary patients, and you can check yourself out if you want.
Other than that, I have found Somatic Experiencing and brain spotting to be helpful in reducing dissociation.
