I used to years ago. They were quite debilitating. I practiced self care & taking that literal step back & thinking thru things logically, realistically helped me overcome a lot. Right now I just have social anxiety. But I'm also an introvert so I don't like social situations anyways.
I've only had a couple panic attacks in my life and they had to do with an accident I had. I had ridden my bicycle 20 miles and was tired and crossed a major road a block up from my house. I had thin tires on my bike and rocks can cause problems, so when I saw one in the road, I swerved to not hit it with the tire and didn't see that in the front of a parked truck was a parked car. I hit it and caused $3,500 worth of damage!
I also broke my tooth, had to get stitches on my face and bruises all over. For a couple nights after I had panic attacks from that accident.
I once had a panic attack but it was very brief. I was in the exam hall and everything blacked out, I could not see anything, I felt like my heart and lungs stopped. The experience was very brief, and in a few seconds I became normal.
