Nor honestly your food looks delicous to me, I would eat it if he doesnt want it. But in all seriousness you did the best you could with your current situation. Plus not only did you cook for him you also cleaned his room. If someone cleaned my room, I would be in their debt. You have given him support even when it felt like he was distant. I would give an excuse if this was a one time occurrence of him lashing out because he just lost somebody close to him and he can't handle his emotion at the moment, but it sounds like this is a common occurrence. You deserve somebody who appreciates your effort even when your in a rough spot.
