I've always been confused of how the word "shame" and "guilt" should be used. Also "humiliation" and "embarrassment" I thought shame was more associated to one's future "self". Guilt on the other hand is more associated to one's present "self". So when you don't live up to the expectations of your future self, you are ashamed. When you don't live up to your current expectations, you are found guilty. There's various examples in this article that seems to use shame as the catch-all. It feels like many of these online examples are rather guilt than shame? Humiliation is typically an underserved feeling. Shame on the other hand is internalized and thus deserved. Shame = I am bad Guilt = I did something bad Humiliation = I didn't deserve that Embarrassment = I deserved that https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6143989/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6143989/
