I'm certainly no stranger to panic attacks. However, I've noticed something similar yet different in the last few months. I seem to have the same symptoms of the panic attacks except that, instead of feelings of fear, impending doom, etc., I have feelings of anger, rage, and (I hate to say this) revenge. I feel like a different person (dissociation), my heart races, and I feel anxious (my stomach is clenched, for example). These moments last an average of 10-20 minutes. They've occasionally gone on for hours. Might this also count as a "panic attack"? Does anyone have a similar experience?
