Shame about not following food protocol

I need some help on my model below:

C: ate pizza/flatbread for dinner – store bought
T: I should not have eaten that
F: shame/regret
A: immediately wishing I could turn back time, ruminate about how I shouldn’t have eaten that, plan for a longer workout tomorrow to deal with the extra calories I gained today
R: making it harder to be self-compassionate that I made a mistake. (NOT SURE ABOUT R LINE)

Also, I know that flour (such as the dough from the flatbread) makes me sleepy and tired immediately after eating it. So, as soon as I started feeling sleepy, my ruminating thoughts became more frequent and intense.
