Is it a panic attack?

I come in late to school all the time there's a reason but I can't stand walking into class be everyone judges u or stares and I can't stand that. I came in late and was waking to class and I couldn't calm down and as I started to get closer my breathing increased and also got harder to breathe I'm not sure if there was any other things be I was terrified bout my breathing what was that was it a panic attack. Btw I'm 13 and I usually came in late but at break so I don't have to go to class but ye wat u think
