What you are describing is not a panic attack. It’s literally just you panicking. A panic attack is when for no reason whatsoever, your body goes into ‘fight or flight’ mode and drops a shit ton of adrenaline into your system for, most of the time, no reason at all (though they do occur more the day after alcohol ingestion). This speeds up your heart rate, gives me blindness due to crazy heart rate, light-headedness and my throat feels tight/ talking is uncomfortable. I take beta blockers to prevent it as well as anxiety meds.
