Panic attacks

So when i was 9, i fainted in public at a school concert. I was onstage surrounded by a lot of people and i started getting hot. Before you know it I woke up in a chair with a whole bunch of people around me. Fast forward to when I was 11 and I would be worried about being late to school because I was perfecting my appearance and I would get hot and dizzy from how overwhelmed i was. And now I’m 16 and my symptoms aren’t as physical but I’ll get a wave of anxiety from one thought like work or fear of death and I’ll start crying and pacing back and forth in my room feeling like everything is going to go terribly wrong and feel like I’m dreaming for about 45 minutes. Could what I be experiencing over all these years be panic attacks?
