What you don't know won't hurt you... or so the old saying goes. Simple, right? If you don't have any knowledge that could cause you pain, then you won't spend time worrying about it.
It turns out some people can attest to that adage from experience, as we learned once Redditor SooziesNoodles asked the online community, "What do you regret finding out?"
Warning: Sensitive material ahead.
"My mother died..."
Giphy
My mother died in a car accident when I was three. I found out from a newspaper article years later that it was her fault. She wasn't paying attention and crossed the yellow line and ended both her life and that of the person in the other car.
"She told me she was moving..."
That my best friend took her own life. She told me she was moving and gave me all her stuff because she said she had a furnished room where she was going. I hadn't heard from her in awhile and she never answered my texts so i looked up her name to see if she had an accident. Nope, it was suicide. The kicker is she had talked me out of it back in 2014 and i wasn't able to be there for her.
"That my mother..."
Giphy
That my mother knew she had cancer a year before she told anyone or rather, a year before she was "diagnosed" after I literally forced her to see a doctor for her then extremely distended stomach.
I was under the impression that we told each other absolutely everything because up until that point, we did. I found out the truth a month after she died when I'd requested all of her cancer-related paperwork from her oncologist.
"My dad informed me..."
My dad informed me when i got back from Iraq that I was the reason he and my mother got a divorce. I never really wanted to join the military anyways, and it messed me up big time. They had financial troubles and my mom sent me care packages quite a lot. Apparently, that put them into bankruptcy, and if I hadn't joined it wouldn't have happened. I just wanted to get out of that house because it was like I didn't exist.
"Found out my girlfriend..."
Found out my girlfriend told my parents I was extremely suicidal and they responded "so? What do you want us to do about that?" and they never brought it up again.
Few months after they kicked me out for textbook depression, I found out my mom cashed out my Uplan (program that froze college tuition prices for me @ cost of 1991 pricing) my grandmother set up and put money in. She used the $25,000 in it to pay off IRS from problems she incurred due to drug addiction.
"That my former best friend..."
Giphy
That my former best friend was really only friends with me because I drove his drunk ass around, and because he wanted to get in my pants.
"Learning from my sister..."
Learning from my sister that my father told her that my mom's mom, was not paralyzed from the waist down because she fell off a fence, it is that she was beaten so badly by the man she was seeing at the time.
"That my mother..."
That my mother doesn't actually care for me but uses me as material to show off how much of a good mother she is and denies it by buttering me up to be more grateful about my life, really hurt.
"I always blamed..."
Giphy
I always blamed my best friends erratic behavior on mental health issues until one day I found her passed out on my toilet and realized that her behavior always got erratic after bathroom visits. Unfortunately, she may have mental health issues but an addiction to certain drugs was the reason for most of her behavior.
"She was convinced..."
My father never wanted me (or children at all) and actually told my mother that if she had me, he'd spend his life making both of us miserable. She was convinced that once he saw me, he'd change his mind. She was very, very wrong.
