Thanks for the response. I have been trying to go about my usual routine knowing that I don't feel quite right and I will continue to do this until my appointment. I've been trying to jog 4 miles on the treadmill at least 5 times a week. I haven't noticed myself being breathless but do get a "not quite right" feeling almost like a disconnect from my brain to my body. I guess this is normal because I don't feel quite right even sitting still. I think I am still trying to process that there is something actually wrong with me.
