Re: need help light headed all the time
You don't say what kind of doctors you've been to -- GPs? Neurologists? And you don't say whether you've gotten second opinions, or...?
The kind of doctor who could tell you whether your panic attacks or anxiety were a real cause of your problem would probably be a psychiatrist.
Consider trying a doctor with a specialty related to your symptoms, but not the same as the doctor(s) you have already seen. A different point or view, or approach, may be more helpful. When you go, make a list of the drugs you have taken, and your experience with them, as best you can remember. That will be something the doctor can use to try to help with a diagnosis.
good luck to you.
