Palpitation?

Hey folks,
I’ll start by saying I have been feeling overly anxious lately. Who hasn’t with this dumb pandemic.

Anyway this morning I woke up and drove my fiancé into work and on our way we were chatting. Out of the blue I started to get this really crazy faint/lightheaded feeling and almost like I couldn’t take a breath. I pulled over and forced myself to cough a few times, then I got this ‘release’ kind of feeling in my chest and limbs and started to feel better. The whole thing lasted maybe 10 seconds. Since it happened I’ve felt weak and nervous. I think it was a palpitation but extra scary since I was driving.

Have these symptoms ever happened to anyone else, specifically the faint feeling? I’ve had palpitations before that made me feel a little dizzy but this one lasted a lot longer.

Thanks!
