Binks have you gotten any help? You do need to go to a Dr that will help you, this isn't right and you don't have to live like this. That is how I felt before my Addison's diagnosis. Maybe you need some Florinef (sp) to help you keep up your BP. Those feelings can be from being to low which you are too. I don't know where you live but I went to Mayo in Mn and they are wonderful there! Please go to a new Dr!
