Hi, did anyone else have this happen? I originally got sick in sep 2009. I started to recover in early 2010, then started to go downward near the end of 2010 or early 2011. I have been fairly steadily going downhill for years, but during the last month got much, much worse. I have been in the hospital twice this month and third time to er. I'm getting worse by the day. I do have Addison's and hypothyroidism, but they are under control, or supposedly are. I know many on here know the feeling I describe as "my body shutting down". Any physical exertion leaves me feeling very sick and lasts for days. I can only make it to the bathroom about 15 ft away. My legs have gotten really weak, really fast. I have had mris and other testing by neuro and doesn't think it is neuro, in nature. It feels like my heart and lungs are working very hard, yet they aren't. Also, had angiogram that came back normal. Anytime I get my heart rate elevated, even in the upper 80s, I feel incredibly sick. I have a serious heat intolerance, and I can't stand for more than maybe a minute without feeling really lightheaded and nauseated. My body shakes after I do get up and go to the bathroom. I have been checked for Lyme on more than one occasion. I feel like it's going to kill me sooner than later, if Drs don't figure it out. I guess I want to hear reasons I shouldn't think I'm going to die. I know it sounds melodramatic, but that is what I instinctual feel. Thank you so much much for reading.
