Exactly how I felt. I was only out for maybe half a second and I barely hit my head at all but we have the same symptoms. It took me over a month to settle down and realize I was really badly hurt. By then I'd wasted a lot of time when I should have been resting. In fact, I went to work the day after the concussion even though I was confused out of my mind. I just had no idea.

You need cogitive rest and physical rest.

I am a triathlete for hobby and I've put it off for an entire year. That's a bold statement of how I'm doing. It's not good and it's worth the time to heal. So far I haven't gone nuts. (so far.)
