Hi seeker,
Humiliation unfortunately is a term that often applied to my upbringing. The sad part of that is that I don't think my parents intended to be that way, they just believed the spare the rod stuff, and in trying to joke or smart remark us out of sadness, and a child who reacts angrily is a defiant child. This is in me, and I have to work mightily on it with my daughter. The not hitting is easy for me. Trying to react healthily to her anger and sadness is a big test.
I was crushed by undergrad evals sometimes too and I think definitely sometimes they were personal --I was so glad for the classes I had that were more anonymous because they were large lecture classes.
I found writing classes to be especially like what you are describing; one prof loved my writing and another was completely exasperated and critical of it. Of course, I tended to believe the harsh criticism way more than the affirmative response.
Looking at it as one person's opinion is definitely a position I am striving for.
