In one sense, no, you did not want to, but you preferred it over the consequences of not getting up. It IS, in that very real sense, what you wanted to do, more than what you wanted (felt like doing.)
But the point here is not that argument. The point is that we always act according to desires, and when we conceive of ourselves as acting against our desires, we are only acting against some of them. When we want to bash someone online, that our better judgement stops us, it is because there is also something, besides bashing someone "who desperately needs it", that we also want, and which, at least at the moment of decision, we prefer over the other desire. Many here use that term —'prefer'— instead of "want".
