Epic Fail

So I was diagnosed with sports induced asthma a while ago. Well, the medicine didn't work and I went on surviving feeling exhausted after every time I exercised. A few weeks ago I went to a lung specialist to see what was up. She right off the bat ruled out asthma. Great months after I was diagnosed I was going to be re-diagnosed. If only it were that simple. She sent me to get test after test and every time there was a lead on something, it was dashed to pieces after another test was done. Finally, when I saw her she had no idea what was wrong with me. What was the next step? FUCK! the doctor didn't even know. I mean I'm not dying or anything but running is very difficult and any exercise throws me into a spasm of pain. The medical field has no idea what to do next. Their tests showed nothing so they in turn can't do shit. AWWWWWWWWWWWW! It just amazes me that there seems to be no fix. This is bullshit and I am scared and frustrated, and amazed that someone can pay soo much for absolutely no answers.
