I got Covid last March and have had long Covid since then. My Dr. does believe it exists and for that I have been most thankful. His belief is that I will get better and that has been true. I went through periods of being so dizzy, brain fog, anxiety, shortness of breath and fatigue that I could hardly function at all. I was getting afraid to drive somedays as my focus, attention, and alertness were all off plus being dizzy. If I tried cooking something I would have to sit down 3-4 times because I was too dizzy to stand for more than couple minutes. I use the word Dizzy but that is not quite accurate to the experience. I am sure some of you know what I mean. I told my Dr. once I feel like my brain is swollen doesn't fit in my head. Thick headed? Woozy? Would need a 2 hour nap every afternoon I would be so wiped out. Now I have good days where I feel totally normal. I chose not to take anything to treat symptoms as the options of different supplements, medications etc. etc. to try seemed too overwhelming. My challenge now is when I have a "good" day, I believe I might be well finally but find that's not the way it is. But I am improving so try be hopeful. Today I took my dog to the park and walked which I had not been able to do for a long time. I am encouraged. To all of you, try to stay hopeful and be sure to have a Doc who believes you.
