So about 5-6yrs ago I all of a sudden I got extreme fatigue that was all day everyday for over a year. On a scale from 1-10, it was a 12. Tiredness to the point of feeling faint & dizzy like I m going to pass out. I would have to leave the store and go sit in my car until the feeling would pass, so I could go home. It has gone from that 12 to about a 5, but now I also feel sick to my stomach all the time. I also have bad heart racing and sometimes flip flopping feeling and really bad shortness of breath. I ve had blood test and even a heart monitor once, I m always told the tests are normal. I remember what normal feels like, and it s not this! This isn t even functional.
