I have been dissociating, derealizing, and depersonalizing in episodes in the past year or so. They begin with a slow descent into derealization, followed by a slight headache seemingly toward the front of my brain. In the worse episodes one of my hands goes numb and then it switches to my mouth. Sometimes these episodes are slight, and only derealization and headache are present, while in the severe episode I am very detached from everyone around me and have issues processing language. During these it is also difficult for me to write coherently, often misspelling words I know. I also experience visual distortion, where its almost like I lose my peripheral vision, and long words written down are cut short when I tried to read them. I have a neurologists appointment in a couple months, but I m worried I may need an MRI sooner
