oh love, I feel you. In first grade I got kicked in the head on the playground, absolutely had a concussion and didn't know it. Got in line when recess was over and I felt the build up, so I waved the kids around me away before pressing my hands as hard as I could to my mouth until they were clear, then up chucked everything in my body in one violent burble. they took me to the office and I waited for my dad to come get me, and I couldn't figure out why everyone was staring until he showed up and goes Jesus, girl. You look like Yoda. even your ears are green. cheers dad.
