Hey everyone.  Lately I’ve been feeling really lightheaded and I’ve been having like constant panic attacks. My heart starts beating really fast. I take hydroxyzine three times a day and that’s not working at all.When I lay down flat on my back I’m really dizzy. I went to the ER and they said it was not vertigo but I was having irregular heartbeats and high blood pressure. They gave me some Ativan and some Zofran because I was feeling nauseous. 
I had a CT scan and everything was good.They also gave me medicine for the mild headache that I had.  They just chalked it up to anxiety and sent me home.Has anybody else been feeling like this? I read somewhere that this could be anxiety. I’ve also read that it could be something wrong with my inner ear.
