If this were NSFW, I might answer. Probably not, because it's fucked up my life very hard. Never really recovered. I've never told anyone about it either. At least, if we're talking about the worst moral thing that's happened to us. Talking about things outside of the worst moral things to happen to you, it would probably be my Crohn's disease kicking in at age 17 and in less than a month nearly killing me. I was rendered permanent disabled from it. From "Never knew I even had it" to "blood coming from places it shouldn't be and a 70/30 chance of dying on the operating table" in about 20 days. Or maybe it was hearing my mom say straight to my face in the 6th grade that she wished she'd died during an operation... that was fixed 2 years later. Because she didn't care about anything other than how she felt.
