Panic Attacks

Okay, so I had a panic attack (I don’t know what else to call them) over and IXL (yes, an IXL) about a month ago and it was traumatising because I felt like I was suffocating. I thought it was a one time thing, but then I had another panic attack last night over some school work I missed (it wasn’t hard, I was just overreacting). And while I wasn’t suffocating like before, it was still a bunch of hysterical laugher and sobbing, though they both kind of sound the same so I’m not sure if it was one or the other, but I was crying so I’m going to go with both. Anyways, is this normal? Should I be concerned? Is this just a teenage thing I’ll get over? Whenever I have it I always crawl into my closet, is there a better way to get over them faster?
