Buffering model

Hi, Should I always put urge in the F line when I am buffering? I feel various emotions and I am not sure whether I should put urge or another one, For instance:

C: Work goal to finish filing notes without looking at twitter
T: I’m out of control
F: Shocked
A: Keep looking at Twitter , thought loops where I focus on all the ways I am out of control: eating, work
R: Continue to be out of control
