What deep secrets did your parents reveal after you came out?

My mom secretly suspected I was gay for a long time because apparently my internal struggle with something was painfully obvious, but because she sent me to an all-boys school, she had assumed I had fallen for a boy there instead of feeling like I was trapped in Hell itself.

Also, apparently, my mom was worried I was being sexually abused by my dad as a child, but did nothing about it because of lack of evidence (nothing actually happened afaik), and when I came out she was briefly afraid that me being abused had turned me trans.

What's your story?
