I've always read that panic attacks are those that feel incredibly overwhelming that you feel like a heart attack is coming on. I've never felt that way. Most of my experiences have been what I assumed were anxiety attacks: my heart pounds really fast, I have difficulty breathing, my extremities get numb, I get nauseous, and have reflux symptoms. I shared this experience with a mental health physician and she said these were panic attacks. So just really confused what the difference really is. Thanks very much in advance to whoever responds.
