Yes. I have about 8 years that are sort of fog. I have memory of what happend but it is very different than other years of my life. I was in chronic pain, doctors did not take me seriously, and the ones who seemingly did, but whom I did not agree with their diagnosis, threw all sorts of shit drugs at me. Sometimes I tried them, but it was never for very long. It negatively affected many parts of my life. I felt imprisoned most of those years, an incredible loss of freedom was the overwhelming thought in my mind at the time. I also felt I was not me, not the me I know myself to be, so the time is lost from the life I feel I was supposed to have. Maybe the years are foggy as a defense mechanism. I think it is probably a gift to have an unclear memory of bad times. There is research suggesting taking drugs that affect memory helps treat PTSD before it sets in. When a traumatic bad memory is etched in our brains, and pays like a tape in our heads, it can be extremely anxiety provoking. I’d rather not go back to feeling anxious.
