Brainfog while presenting

I woek remote. I messed up in one of the meetings where i was presenting. I had a real bad brain fog due to migrane / anxiety that resulted in a bad meeting to a point where my coworker had to step in clarify on what i was presenting. Anybody faced this at work? As a result there was some escalaton but not to the point where i can lose my job.. any thoughts to cover up . I will be having a meeting with director where i have to explain myself on what went wrong and i would be orovided feedback:(
