I just recovered from sickness that I had for 4 days. My throat felt like it was on fire, and I couldn't breathe through my nose due to congestion. I mostly laid in bed and watched YouTube videos; I didn't have the energy to play video games :T When I was sick as a little kid, I always watched The Price is Right with my grandma, so not much has changed from then.
Sometimes I feel that changing clothes, getting ready, and taking a shower help me feel less sick despite not really treating the symptoms. It seems more like it's mind over matter though.
