I have had Long COVID for 3 years. I still have Brain Fog which impacts my being able to find words and my short term memory. If I do my breathing exercises and remain as calm as possible it helps some. At times I have laughed and said it is time to guess what Susan/Mom is trying to say. It is really upsetting when it happens in a work meeting. I work remotely as I have all kinds of issues from Long COVID. I have told people I work with closely so they are aware. At times not only can I not find a word, I am thinking one thing but what I say is something else. Good luck with this.
