Let's see:

Any kind of "should" thinking - I could write a damn book detailing the entire ideology that makes thining about certain topics, philosophies, etc give me terrible anxiety and make me want to curl up and cry because I somehow identify whatever it is as the ONLY CORRECT WAY TO EXIST and I'm a vile, disgusting failure for not agreeing or measuring up.

Stoic people with no emotional needs, or those who cured themselves of mental issues through sheer discipline and willpower. So much guilt.

Stories of abuse. So much guilt (this one really stretches back)

Accounts of growing up fast or being ultra-mature and adult by a young age, including total independence by or before age 18. Guilt guilt guilt I'm the worst.

General comparison of ability with anyone - I'm a failure

Some kinds of food. Weird, but I've noticed it. I'm basically allergic to Chinese food in that I'll want to burst into tears halfway through the meal despite no triggers. It's purely chemical, and I still don't stop eating the stuff. :/
