Sick or not we have no right to expect more of someone than they can give. It is just as selfish as one who chooses not to understand illness. If someone is trying and not able to succeed so what. Yes, it feels awful but geesh look at their effort. Compare it to someone who says screw you get over it already. I'd much rather have someone around atleast concerned even if they don't know exactly what to do than one who says screw you get over it.
