Never had an anxiety attack... I'm very calm and mellow, but I could be sitting in a chair and all of sudden I'm breathing like I ran a few laps. It goes away pretty quick but I'm like that was weird!
I thought it was normal honestly... until my cousin noticed me doing it yesterday and he said he has that happen to him too except he'll do a big gasp for air like he forgot to breathe.
yes this shit has happened to me the past couple months.. thought i was developing asthma, ill be just walking and it feels like i lose my breath and i take a big gasp for air and keep walking then it does it again a couple minutes later .. its slowed down this month and rarely happens anymore.. and i have anxiety so i figured that might just be me freakin out or some shit
