Painful wounds reopened

todayi hd an appointment with my vounselor laurie. I hadn't seen her for about a month over the winter break, and I thought I had made great progress in that time, I haven't had any negative thoughts, flashbacks, nightmares.. nothing. I was doing great, or so I thought. My appointment today to continue working through the trauma of my dog being attacked was excruciating. My anxiety levels were sky high and I could hardly tolerate it. Even now, hours later, I can barely stand to think about it. I've been nauseous all day, having flashbacks, using music to drown out the sound of him screaming in pain...to drown out the sound of my own screaming.... I started writing a log today to keep track of how I felt, my anxiety continued to escalate after my appointment, and it got so severe I began to develop a migraine and had to leave class early - in which I almost cried telling my professor. Walking to the bus from class, I couldn't feel my legs, I didn't feel as if I was in control of my body, it was just moving without me. Ir didn't feel like I was looking at myself from outside my body.. It just didn't feel like I was in my body. It was terrifying. I just want to cry all the time.
