This isn't emotionally, but I have a heart murmur (small) and a few years ago I had to do this test where they put me on a treadmill, covered my nose and mouth so I couldn't breath, hooked me up to a computer and I had to run as long as I could without oxygen. God, my chest hurt so bad….then they got me off it and took that thing off my mouth and I spit up all over the place…then they like threw me on the doctor bed for another test…a heart ultrasound…and the girl that did it like jammed the little thingy at the bottom of my throat…I don't know about you, but that's the worst thing I've ever went through…
