Yes exactly! Last night I had a huge panic attack out of nowhere. I dozed off on the sofa and woke about midnight and was panicking in an instant. It hit me like a ton of bricks and didn't go until around 3am. I have felt shaky from it all day today and on edge and this is how it'll probably be the next few days.
These so-called professionals don't seem to have any idea. I have had panic attacks that have lasted less than a half hour, but more often than not they last for hours at a time. Often, they'll go on for ages, then start to subside then after a few minutes they'll come back again. It's absolutely miserable
