Am I selfish for not cleaning my drunk friend's house?

I was drinking with some college friends and this one friend of mine, whose house we were drinking at, got severely drunk. Our other 2 friends left when it was getting late and cleaned up their own drinks before leaving, which I did too. Before leaving they told me to clean up after myself as well as my friend as she's wayyy too drunk to do it properly. Since I was pretty drunk myself and had a splitting headache, coupled with the fact that it was getting dark outside, I just cleaned up after myself and left. The next day all of them blasted me for being selfish and inconsiderate as I didn't clean up after a drunk friend. I reminded them that it's not my job to clean up after her and that I have taken care of her when she's gotten drunk at public places before, and if they're so concerned about her then they should've themselves cleaned up after her. Now they're all mad at me and expect me to apologize. Am I selfish?
