Hi,
I've had panic attacks on and off for the last 15 years. Usually i feel like i'm going to have a heartattack and i'm going to die. In the most extreme cases, however, I get in panic mode so much that I call an ambulance and in the waiting time actually feel my life slipping away out of my body. This is the most frightening experience i've ever had and puts me in purely instinct mode where i for example run towards the ambulance in my underpants, yelling "I'm going to die". Afterwards the feeling i've had is unsettling to even think about.
Does anyone recognize this symptom during a panic attack or can someone try to explain what happens in my body that i experience this? I can't really find anything about this on the internet.
