Looking at how my past "should have" been different

This morning I was taking a look at how my past should have different than how it actually was. I was wondering if could get some feedback on a model about it.

T – When I was a child, I shouldn’t have let my cousin tie me to a tree with toilet paper.
F – Frustrated
A – Spin in my mind about, not let it go (years later), beat myself up over what I should have done

I was wondering what my result would be and if my model looks correct? Is a past experience actually supposed to be in the C line? For some reason, it made me really emotional to look at this. I’ve never forgave myself for what I didn’t do. I would LOVE some feedback on this model to understand it better. Thanks!
