Worst Panic Attack: Re-living a Frightening Situation through Flashbacks

My worst panic attacks were in the aftermath of an accident. I saw a severe motorcycle crash that involved someone I care about. Of course, at the time I experienced panic symptoms.

What I didn't expect was after the accident, I would get the same symptoms and see flashes of the accident again. Sometimes it would be random. I would suddenly see the crash in my mind for no reason.

Other times, there would be a trigger - the sound of a motorcycle engine, seeing a motorcycle or a fast-moving vehicle - and I would get all the same panic symptoms again. Racing heart, rapid breathing, shaking...

After self-help, therapy, and the passage of time, the panic attacks eventually went away.
