Portia Conn On Having Anxiety, Panic Attacks and Depersonalization 

I have been helping a friend going through what he experiences... panic attack and then next day turns into depersonalization and lasts a week. I am learning the depersonalizaiont is a result of a rush of adrenaline. And, if you've heard of Fight or Flight.. there is also Freeze and Fawn. And even during the anxiety attack he will feel like he is calm, but his body is going through all the symptoms of an attack. Anyone suffering, look up also EFT, EDMR, and definitely do breathing exercises when it is happening. The brain is confused thinking it is in danger when it is not, and thus results with faster heart rates, numbness in the hands and feet, etc. so doing the EFT and breathing can help "tell" the brain it is safe and not in danger.
