I went through the same thing when I relapsed after four years. It was miserable. It was never that bad back before I got into recovery. I remember standing at the big drill press I was running and out of nowhere I was hit with fear. I don't know what the fear was about, but I started crying. I would get the palpitations too. Thank God I made it back into recovery after a month.
