Hey Third Rider,
Some of your posts sound exactly like my wife's experience, who btw, is an ENFJ. She had panic attacks every night, wouldn't sleep, and when she did she would wake me up in the middle of the night thinking she was going to have a heart attack (panic attacks and indigestion are often mistaken for heart attacks). Initially I could talk to her and calm her down, but the attacks became worse with time, to the point where she HAD to get medical help.
They gave her zoloft, and frankly, it worked very well. I'm not saying that they are right for everyone, or that there are no alternative treatments, but in my wife's case it was the only thing that helped her.
I hope this helps in some way.
