I am sorry about the death in your family. It appears to me that your symptoms are anxiety related, they can mimic all kinds of things, and since your cardio exam was good and your symptoms are not too severe, I would say this is the problem, Anxiety is not fun, and it can definitely cause all kinds of "unreal" feelings. I have anxiety at times, and when I do, I am a mess, so, I can relate to what you are going through. I, too, have had that gasping feeling when I am just about to fall asleep, I have not heard of anyone else having that, I hate that feeling, my heart is always normal when I check it afterwards, so is my b/p, but, I sure hate it. I do not have it all the time, and I am thankful for that. So, you see, you are not alone. :)
Wow, I am full of forget today :P
Also been having a mild headache as well. I dont really get headaches at all so this is new to me. I feel it most where the neck meats the back of the head. Also when I shake my head back and forth it kinda feels like my brain is loose. I know that sounds crazy, but its the best way to describe it.
Sorry I forgot to mention, The Nuke Stress Test and Echo came back solid with no problems.
