Experiencing Extreme Dizziness and Fainting: Any Advice?

I tend to have that when I have panic or anxiety attacks

My doctor diagnosed me with panic disorder after that.

Yep. I hyperventilated the first panic attack I had. I thought it was so strange that I nearly blacked out from breathing too much, when I had trouble catching my breath.

Yes!! Starts with stomach cramping, diahrrea, severe itching and hives, blood pressure drops, blurred vision, feels like throat closing then passing out. Horrible!!
