Exhausted. Here's the deal: when you get a concussion you should not ride on a roller coaster, particularly one with a lot of velocity, centrifugal force, and sudden changes in direction. Also, one should take care not to bump their head again. One should attempt to sleep much, eat regularly, avoid stress and strike a balance between sufficient rest and resuming normal life.

If you disregard this stuff, your brain relapses to an earlier stage in the recovery process, setting hard won progress back.

I do not feel good. Just getting through the day is consuming all the strength I have. And for whatever reason, I would never have suspected that the roller coaster might not be a good idea. :-(
