I don't know about the oxygen thing.

Here is what I do know.... I get in these episodes where I feel like my bones are trying to jump right out of my skin. My heart races, I am extremely restless. I feel like I could sprint for two or three miles. I used to think it was something physical going on, but now that I'm older I realize it's something to do with my mental state effecting my physical sensations. I remember sitting in the doctor's office rocking back and forth getting more and more "frenzied" or whatever, and wondering why in the world they didn't care how much distress I was in. This was when I was like 19 or 20 years old.

When you get that physical feeling do you also feel very aggitated and irritable?

Also, do you have any type of diagnosis? If this is really causing you trouble you may want to see a doctor about it.
