Is this what is a panic attack?

I was jus laying down a while ago with my mind in thoughts of the issue my mmom's havingwith the ccontractor. Suddenly I could feel my heart beat very fast... I felt a little breathless n it felt as if I would have a heart attack the way my heart was beating. I sat up n then it subsided.

Is this what is a panic attack?

It could be.... or it could be palpitations not related to anxiety (some other medical issue), or an oesophageal spasm. They all feel very similar.

If you are experiencing those symptoms, best to go to a doctor and get them checked out.

It's probably a reaction to stress, but possibly not a full blown panic attack.

I've wondered the same thing. I've felt similar feelings in situations where I felt very self-conscious, and I thought I was having a panic attack, but when I looked it up online many of the symptoms didn't fit what I experienced.

Regardless, there's a chance that what you're experiencing could end up developing into full-blown panic attacks, so it's probably a good idea to try to address the issue if it becomes a regular occurrence.
