It really stinks but... resting all the time is the best thing you can do for yourself right now. That way your brain has more time to rest and heal.
But at least after a while you'll be able to gradually introduce gentle activities in your days, such as watching TV, going on gentle walks, talking etc. Though you shouldn't get into sports or any rigorous activities involving intense shaking of the head until you're completely symptom-free, as that could cause Second-Impact Syndrome.
