OMG, no it is NOT fine. You know something is wrong. It is your body. I really hope you find a doctor that gives a shit. I am so sorry you are going through this and getting tossed around. So not cool. I worry about dementia and Alzheimer's a lot, maybe because I worked with seniors for so long but things happen to me that I think that is the only explanation that it might be coming. It's scary AF. You are so young, too... too young for this. I really do hope you get some answers from a doctor that cares. <3
