Model question


I have a situation that is weighing heavy on me and I tried my hand at a model. Here it is:
C: I made up an excuse as to why I cancelled 2 classes at Pilates. I lied in essence and I was caught in that lie.
T: Why did I feel it necessary to lie?
F: shame
A: continue to be scared to be honest
R: I lose respect for myself

If this model is correct, I don’t really know where to go with this? Curiosity as to why I felt it necessary to fib? I felt so bad for late cancelling 2 classes in a row. I just couldn’t make them at the last minute with what I felt was not a good enough reason and I felt bad, so I tried to make it sound more serious. Did I hurt anyone? No, the classes were prepaid so they weren’t losing any money.
My question is where do I go after this type of model? I just want to feel better.

Any insight would be valuable. Thank you.
