Dizzy everyday 😔

I'm curious if anyone else has this - I am either lightheaded or actually dizzy everyday randomly. I'm hydrated enough, I eat enough during the day, and when I went to the doctor last week - all vitals, sugars, proteins, and blood work all came back normal and fine. My doctor wasn't concerned either and said it's just another symptom. Anyone else dealing with this? It's just super unpleasant and really hindering me at work and at home.Â
