This is just a by the by, but in British English "feeling poorly" mostly means that you are ill. Amusingly it's become slightly euphemistic, so if someone is "a bit poorly" they probably have sniffles or a minor fever. If they are "very poorly" then you probably heard it from a hospital and they're just about dead.

Thus "I feel badly" ... "ok, what did you do?" vs. "I feel poorly" ... "ok, I'll get a bucket."
