Hello I hope things are going better for you at this time. There are many thing that help with flashbacks, and your therapist can help you with the appropriate way to deal with the flashbacks. Writing, dancing, martial arts are just some ways to help with flashbacks, but you need to have your therapist establish your best regulator, so that you dont harm yourself mentally from the wrong therapeutic tool. I hope the best for you in your therapy Take care Sincerely Soidhonia
