Like you, Crystal, I have experienced many panic attacks. On at least three or four occasions, I have ended-up in the emergency room, and one time the attack was so severe, that I almost called the paramedics. I know that they can be very scary, and certainly they can make you feel as if something terrible is going to happen, such as a heart attack or seizure, that you mentioned. But panic attacks are harmless, and will not cause these severe conditions.
Anxiety disorders, including panic attacks, are treatable, but you must seek help. I see a psychiatrist, and she is in charge of my mental health. She has provided me with a diagnosis, a treatment plan, and has started me on an anti-depressant. Part of my treatment plan includes participating in cognitive behavioral therapy (CBT). I started CBT several weeks ago.
Again, welcome to Anxiety Zone. The very best to you, Crystal!... Chuck
