just anxiety?

so i’ve been having these weird random times where all of a sudden i feel like i can’t breathe and then i get a little dizzy. i’m not entirely sure what trigger them, but i think they’re panic attacks. it starts out with something freaking me out a little then it launches into me not breathing, then that freaking me out, then having to calm myself down for several minutes by trying to breathe. i get dizzy and sometimes feel almost like i’m going to pass out. this started a couple months ago. i’m not sure if i should go somewhere and get checked out, or if i’m just having anxiety. it’s kind of scary. i just woke up having one and that was really freaky.
