I had to go to a class, so I stood back up, dealt with the
tiredness,
and such,
and took a 8 minute bath or so. As soon as I got out of the bath my chest started pounding, I could feel my heart in my neck just pounding, I was very tired, didn't want to move, and I was breathing rapidly again, short breaths. So, I laid down on the bed, no change, tried to lay on my side, it only made breathing a bit harder.
