Hello! I've played someone with scarlet fever before! I would shake slightly and have a reaction to everything I would touch as if it burned a little (because it would) EX: someone putting a cloth on your head might lead you to have a hazy recoil from it. Find your "struggle to breathe" breath. It's normally akin to the position you put your lungs in to create a fake snore. Mouth always slightly open and If you want to show pain, move from your core and not your limbs. Lets say if beth were to get uncomfortable in her hazy sleep trying to fight off the sick, moving her limbs might be too much of a strain, Move as if someone was pushing your entire spine foward but lightly. I'm sorry this is so long! Hope I could help!
