Hi I know it is hard to stay in the day but until your doctor appointment I would try hard to not get ahead of yourself. For me when I read about some health problems it sends fear into me which helps me in no way. What type of doctor have you seen and who mentioned or dx you with Disautonomia? Are you under any other treatment then supplements? I know it is hard to not get scared cause trust me life feels that way but I am really practicing to be more calm and not get ahead of myself. I hope your doctor can give you some answers
