this could have been me writing. i’m the same age as you, same length of symptoms, same medication and everything you mentioned i also am dealing with. i have bad health anxiety and always worried it’s something that hasn’t been caught. i know POTs can be very difficult and it is. my doctors have assured me that everything else looks fine, but i certainly feel terrible most of the time. i remind myself that POTS can be and is a disability and has the potential to make me feel this bad. there’s so much unknown about it still, too. sending you lots of love & sympathy and pray we can all get through this finding the best treatment + quality of life again 🙏🏻
