I'm constantly tired since 2019. Over the years I’m less and less able to endure a full day and the stress of work, trips, parties, or even vacations. I did plenty of exams during the last years, brain MRIs, electroencephalogram, heart exams, vein exams, blood tests, virus tests, but none of them showed anything wrong. I don't know if I suffer from CFS (Chronic Fatigue Syndrome) or anything else, but sometimes, my disease turn into peaks during some weeks. During these peaks, my symptoms are really uncomfortable, to not say a real hell to survive: 1. It first starts with high-fatigue and fainting feelings. 2. Followed by a feeling of being reboot during the next few hours. It is really hard to explain, it is like you forget everything and you don't know where you are, even if you remember it. 3. Then comes the symptoms that can last several days or weeks: * A Depersonalization-Derealization disorder (DD). * An hard feeling of close death, like if you will die in the near days. This is the most annoying and terrifying symptom. * Various cognitive slowdown (thinking / loss of memory...) * Tachycardia by standing or walking * Feeling of pressures in the head * Altered vision * Difficulty falling asleep * Persistence fatigue, even if you sleep more than 10 hours a night Unfortunately, each time, the peak become stronger and harder to endure. I think I didn't tolerate the stress of the Christmas holidays, with my girlfriend we had guests and many things to prepare for the 24th Dec., then didn't sleep so much and were to the family during the whole 25th day. When we came back home it started, and I really though I was going to die. I felt so bad, I went to bed thinking I had a 50-50 chance of surviving (or less). Since this day, the feeling of close death is so hard I sometimes wonder if I fighting to survive is reasonable, I feel condemned. And the DD make me sometimes feel I'm already not alive anymore... I already experienced that so I know it can just be a feeling and it won't happen, but since it's stronger each time, it really makes me feel something goes wrong in my body and I’m not gonna recover this time. Does anyone ever experienced that? :(
