Anxiety attacks ain't no joke. I feel for ya there.
I was hospitalized twice, once for days while they ran tests to see what was wrong.
Tunnel vision, near loss of consciousness, blood pressure WAY up there, just wanting to crawl right out of my skin and go somewhere else.
Went to my primary after 2nd time and she listened and looked at the trainee she had with her and asked what she thought.
"panic induced near symbiosis"
Which of course means I had a panic attack and almost blacked out.
I still get them some but now that I know what it is I can talk myself down. Well I don't really talk myself down I just recognize what it is and try my best to ignore it and it eventually gets tired and goes away.
Best of luck to you
