Hello all, I am really not doing good at all and need help. I've been dealing with severe anxiety for 2 years now.im starting to have panic attacks like I've NEVER experienced before. 20/10 level.

I'm worried that they are seizures and not panic attacks. For example yesterday I had one on the way to a job interview. I was anxious and then my hands started to go numb. Then began the extreme panic and severe dizziness. I was driving on the highway and desperately tried to pull over. Once I pulled over it got worse. My hands were frozen into claws. I felt like I was seconds away from passing out. I couldn't do anything but lean over, cry and pray and pray for it to end. It lasted for about 45 minutes before I could come down.

Now I'm not unfamiliar with panic attacks. But this... I can't handle this. It's 20/10 panic, fear like I've never experienced before. The numbness always starts in my hands and sometimes spreads all over my body. My hands will seize up into like claws which are very hard to move and usually this will last around 5 to 10 minutes. The extreme dizziness and feeling like I'm going to pass out is so bad when this happens that I have a hard time walking. 

Please please someone tell me if these are panic symptoms or if I should be concerned about seizures. I don't have health insurance, have no money so I can't see my primary. But I went to the emergency room a couple weeks ago where they told me I am perfectly physically healthy. I'm debating on whether or not to go to the emergency room again because I'm terrified of this happening and it's happened 2 days in a row now.

Also, if they are seizures can the er diagnose that? I don't have money to see a specialist and I'm terrified
