There was a time I made an update on one of our client's e-commerce website sign-up page. The update caused a bug that allowed new users to create an account without actually creating an account.

The code block meant to save user credentials (i.e email address and password) to the database was commented out for some reasons I still can't remember to this day. After registration new users had their session created just as normal but in reality they have no recorded account on the platform. This shit went on like this for a whole week affecting over 350 new customers before the devil sent me a DM.

I got a call from my boss on that weekend that some users who had made purchases recently can't access their account from a different device and cannot also update their password. Nobody likes duty calls on a weekend, I grudgingly and sluggishly opened up my PC to create a quick fix but when I saw what the problem was I shut down my PC immediately, I ran into the shower like I was being chased by a ghost, I kept screaming "what tha fuck! what tha fuck!!" cus I knew hell was about to break loose.

At that moment everything seemed off as if I could feel everything, I felt the water dripping down my spine, I could hear the tiniest of sound. I thought about the 350 new customers the client just lost, I imagined the raving anger on the face of my boss, I thought about how dumb my colleagues would think I was for such a stupid long running bug.

I wondered through all possible solutions that could save me from this embarrassment.
-- "If this shitty client would have just allowed us verify users email before usage things wouldn't have gotten to this extent"
-- "Should I call the customers to get their email address using their provided telephone?... No they'd think I'm a scammer"
-- "Should I tell my boss the database was hacked? Pffft hack my a**",
-- "Should I create a page for the affected users to re-verify their email address and password? No, some sessions may have expired"
-- "Or maybe this the best time to quit this f*ckn job!"
... Different thoughts from all four corners of the bathroom made it a really long bath. Finally, I decided it was best I told my boss what had happened. So I fixed the code, called my boss the next day and explained the situation on ground to him and yes he was furious. "What a silly mistake..!" he raged and raged. See me in my office by Monday.
That night felt longer than usual, I couldn't sleep properly. I felt pity for the client and I blamed it all on myself... yeah the "silly mistake", I could have been more careful.

Monday came boss wasn't at the office, Tuesday, Wednesday, Thursday, Friday not available. Next week he was around and when we both met the discussion was about a different project. I tried briefing him about last week incident, he seems not to recall and demands we focus on the current project.

However, over three hundred and fifty customers swept under the carpet courtesy of me. I still felt the guilt of that f*ck up till this day.
