The diet coke isn't a good thing....but I don't get why you're punishing yourself so extremely....food won't make your flare worse. It can give you more discomfort and probably exacerbate diarrhea, however, so base it on that fact, not that your UC will be worse.
Once it's all out, you should be feeling back on track.
It's better to make the choices consciously and know the outcome rather than do it impulsively and then punish yourself afterward....can get into a negative cycle which isn't good for dealing with UC.
Hope you feel better soon,
