I have a story here that might help.
The last severe panic attack I had was after I had left the job in Utah I posted about having to leave. I spent a night in Vernal, Utah, a city of about 30,000, in a room at the Best Western. I had been given a ride by a co-worker and was so grateful as I do not have a car and I was working 37 miles away out in the sticks.
Anyway, getting to the point. I am alone in this hotel room and out of nowhere I had this intense panic attack and I truly thought I was going to die of a heart attack. It got to the point where I managed to get myself to a gas station around the corner to find aspirin as I thought gee, maybe I can head this off at the pass if it is a heart attack.
Didn't work. Didn't slow the heart rate or slow my mind down. So I called the front desk and spoke to the night auditor about where I might find medical care. By this point I am in a total panic about the potential hospital bill too as I don't have insurance, and my panic attack has not subsided.
But here's the blessing, the wonderful thing that happened to me out of nowhere. I went down to the front desk and spoke to the night auditor for a bit and it turned out she has had panic attacks and was able to talk me down out of it a bit so that I could go back up to my room and sit still. What a miracle that was! To find such support randomly like that and to not have a huge hospital bill hanging over my head like that! My advice is if you can find someone to talk to, someone who gets it - it seems to work wonders, at least it does for me.
And that's probably why most of us are here, anyway. We get it, if you know what I mean.
