First Anxiety Attack??

Stephanie • Southern roots. Jersey attitude.
I'm not sure what just happened. I was lying on the loveseat reading while my hubby played a video game, and all of a sudden I feel like I can't get enough air with each breath. I try adjusting my position. Nothing. I feel this sensation near my diaphragm like its tensed up. Then as I'm trying to get my breath I'm all of a sudden aware that my heart is pounding. When I go to feel my pulse I realize my fingertips are tingling...
I am now laying in bed, and I can breathe a little better but the sensations are all still present. I've never felt this before and it's kinda scary..
Is this an anxiety attack?? If not, what's wrong with me? If so, how do make it stop??
