Is this normal for a panic attack?

Any help you can give would be incredibly appreciated! This is all so new and scary for me. I have been crying myself to sleep a lot these last few nights because I feel like I am going crazy and losing myself.  I even worry that I will die. Out of nowhere I am pretty sure I had a panic attack while driving my car a month ago. It came from out of nowhere. My heart began to race, my leg, arm and hand started to tingle and go numb. Difficulty catching my breath.  My head tingled. Then I felt a warmth pass over my head and things started to look fuzzy and go dark. I began to pass out. But.. didn't. I was in Las Vegas traffic and for those minutes lost any sense of caring if I took out another car as I tried to get to the shoulder.  I felt myself blacking out again and had my 8 year old call 911. I thought it was a stroke or a heart attack. I am on blood thinners from a stroke I had when I was 32. I was transported to the hospital and since they couldn't find anything (except my blood was clotting a little too much) they said it was a mini stroke. Then.. almost one month later (last Monday) it happened again! I knew my blood was fine this time. And ironically it happened again in the driver seat driving kids to school. So every time I got in the driver seat all last week my heart would race, head would tingle and that fight or flight feeling was strong!!!  Is is possible to have the car be my trigger when I have NO reason at all to be fearful or stressed out with the car?   I have an appointment this coming week to meet with a therapist. I haven't talked to a doctor about it because I am worried they will not be sensitive about it.  This is so new to me. I don't know why it's happening!!! I am 38... and my marriage, our finances and everything else is finally at a good place. I don't know what underlying stress or fear or worries that could cause this.  I feel so helpless because I have no freaking idea where this is coming from.  It's even keeping me on edge all day long.

I have found with my anxiety that if I have anxiety while doing something specific, my thoughts do attach themselves to being fearful of that one thing after that.
It is good to know that you are getting checked out for your health to make sure everything is okay.
But it does seem to be part of how anxiety works, if you have one time of anxiety while doing something..the anxiety seems to return while doing that again.
It is a thought process that can be undone though. I wish you the best of luck with everything.

SP, sometimes what we do to fight back or not surrender to panic/anxiety seems strange,
if my car was a trigger, "I would kick a tire and inform it that it was not so scary".

If that didn’t work I would calmly get inside and inform it that I had called a salvage yard,
and you may get recycled!

I Pray you are already better.
