@Nelson G. - While I believe that symptoms can be made worse by stress and mental health issues such as anxiety, depression, and other things, I know that dysautonomia is not caused by those things. I have had anxiety for a while, and in fact, my anxiety started after I got dysautonomia, not before. I think doctors sometimes have a tendency to say things like that because dysautonomia is a disease of the nervous system. Your nervous system controls every single system in your body, so naturally if your nervous system is messed up, then almost every other system is going to be messed up too. Doctors have a hard time seeing that the body is all connected, so sometimes they can say things like because they truly don't know what is going on. Dysautonomia is a complicated disease that is very misunderstood. I once thought that it was all in my head too, so I stopped going to doctors thinking, "If it is all in my head and I just ignore it, it will all go away." In fact it did not, but only got worse. If I could make my disease go away by going to therapy and taking anti-anxiety meds (which I have also tried, with no effect), then I would. But it doesn't seem to work that way.
