Glad to know you feel better now Yes, the mind has a huge power over the body and stress can cause all sorts of symptoms. It might also be low blood pressure that caused the dizziness and nausea in the first place, which led to the panic attack. It can do that, it happened to me a few times and I felt like that, about to blackout with nausea. That can happen if you're too tired or dehydrated, or when your blood sugar is too low. The best thing to do in that case is to do what you did, to lie down and relax and try to sip some water or juice.
