Was this a panic attack?

I’m basically 17+6 today and yesterday at work I think I might have had a panic attack? For some context I work in a very face paced setting especially on Fridays because it’s our truck day and I have a department I’m responsible for so from 10am-12:30pm I was lifting boxes, bending over, and walking back and forth throughout my dept and the store was feeling a little out of breath but went on my lunch felt better and went back to work for another 2 hours doing the same thing and then decided I just needed another 15min to grab some water, well as I’m sitting down out of nowhere I just start to feel a little dizzy and I can feel my body getting warmer, in that moment I thought I was going to pass out and I could literally feel my heart rate rising it got all the way to 186, after a few minutes of breathing I got it down to 120-130 Range, and then about 15 min later it spiked back up to the 180s again, this time I called my mom to come get me in a panic, I was able to get it down to the 140s until she came to get me, and then again in the car I had another mini panic attack where it got up to 180. Once I had gotten home and on the couch to lay down we finally got it to go down to the 110 - 120 range. Was this my anxiety? What was this? It was just SO random! I wasn’t even worried about anything it just suddenly hit me out of nowhere
