What’s the worst thing you’ve ever done?

I’m in a reflective mood, and it’s got me thinking about something I did a few years ago which is probably the thing I’m most deeply ashamed of.

There was a coworker who really rubbed me up the wrong way. I was very unhappy at the time, and going through an awful time personally. She would make snide comments about me, do things with my family members (who were colleagues too) which really got my back up, I felt like she judged me harshly and was pretty rude. Along with another colleague they made three or four very nasty comments which still stick with me.

Instead of raising a grievance, which I should have done, I took to posting about her on another website (along the lines of Mumsnet), not realising she used it too. She saw the posts and reported me, and I ended up facing a meeting with HR and a senior partner of the firm I was working in. It damaged my reputation within the firm forever and I ended up leaving after not being offered a promotion. I still feel ashamed of it now, nearly half a decade on, and feel like it’s tarred me forever.

Whats the worst thing you’ve ever done?

Amongst others but when i was early / mid 20s i dated a man who was effectively my best friend but unfortunately i didn’t fancy him at all.
He was so sweet; a geeky weedy type.
I bought him new clothes and made sure I did his hair for him before we went out. I bought him weights to get some muscles. If he didn’t do this stuff I would pick a fight. I picked fights with him over various random things and i kissed two other men on a girls holiday -I did tell him but he always forgave me everything.
I strung him on for almost 2 years before I finished things.
Life has a weird way of working things out and i heard from a mutual friend that he met a girl on a night out a couple of months later.
A bit of facebook stalking suggested she’s absolutely beautiful- way prettier than I was.
They’ve been together ever since.
This was 16/17 years ago and I’m ashamed of myself, I have grown up a lot.

Back in my 20’s I had a really good male friend. He looked after me when I had my heart broken and was always there for me when I needed someone - even when my misfortune was my own fault. I knew that he was hoping for more than friendship and honestly I had feelings for him too, but I resolutely kept him as “just a friend” because our cosy situation with no strings and no pressure suited me just fine. I think I assumed we’d end up together one day but wasn’t ready to commit. Meanwhile I shagged around with a string of randoms who meant nothing to me, just because I could, and I wasn’t remotely discreet about it. Eventually he pulled away from me and stopped calling, and I had the nerve to be hurt and angry…until I grew up a bit and examined my own behaviour. Nobody’s ever been kinder to me, and I’ll always hate myself for hurting him.

Would you ever reach out to him?

I know this wasn’t intended to be an uplifting thread but this has been enormously helpful for me. I have spent my entire adulthood beating myself up for poor behaviour in the past (usually drink fuelled) to the point I have been very mentally low. I cut off every friendship because I was so ashamed of my behaviour and have spent adult life very lonely with no ties to earlier friendships.

It is very reassuring to read that other people have made mistakes and perhaps I can forgive myself.

I’m not sure what my worst thing is but I was very aggressive when I first started drinking at 18, behaved horrifically to parents and boyfriends. Made much more sense when I was diagnosed with ADHD as an adult and realised alcohol just wasn’t for me

I too have found this to be a really helpful thread personally. Have spent 20 years beating myself up about certain events and even now think very negatively about some of my behaviours and it's been really useful to see that actually I'm not some unique horror.

I'd also agree with some PPs about the messages gained in childhood about what is acceptable/ moral and how it impacts the way I have behaved.

My husband used to pick his toenails and put the bits of nail on the arm rest of the sofa. So I put them in his mashed potato.

It's only what he deserved! 🤷‍♀️

As a student, I worked in a pub where a regular complained about me loudly and rudely for putting 5ml too much lemonade in his lager top. He came in a couple of days later for pie and chips. I emptied the contents of the kitchen insect zapper into the pie filling, stirred, puff pastry top, in the oven, parsley sprinkle and served with a beatific smile.

I fleetingly worried that he might die, but it passed (and he didn’t).

Ah, who remembers Fly Cemetery at school dinners! 🤣

DreamyJade · 20/04/2026 23:24

I’ve posted this before. We used to have a rented TV in the 80s that you had to put 50p pieces in. When I was about 10 I broke into it with a knife and stole all the money. It was a fortune to my 10 year old self. I took all the kids in our street on the bus to the seaside for a day out.

Forty years on, my Mum still believes that we’d been burgled.

Woodfiresareamazing · 20/04/2026 23:22

I'm old now, so I've done many bad things.

On one memorable occasion I peed in the flower planter on the rooftop of a church in Catania, Sicily.
It was cold and dark, and I was desperate...

The worst thing I've ever done that I'm willing to post on the Internet is what I did to my poor mum when I was a kid.

She had this ugly little brass imp ornament and I kept moving it about and denying it. Creeped her the fuck out so she threw it away. I got it out of the bin and put it back. She freaked out, threw it away, I would go through the bins and hang onto it waiting for the perfect moment to put it back. I thought her freaking out was funny. I was young and didn't understand that she was genuinely scared and convinced something supernatural/ demonic was going on.

I confessed years later. She was as mad as hell but also relieved.

Looking back it was a horrible thing to do, but at the time I thought it was funny.

Oops. Your poor Mum. I'd have been shitting myself!!

So many. Aged 14 I used to get followed by men in cars when walking my dog early evening. I got in the car with one and we had some heavy petting. Then went home .

I used to steal a lot too .

Got into fights .

Not proud of it.

I was a child, maybe 10 so old enough to know better. Parents were alcoholics so I was left to my own devices a lot.
I loved animals and was desperate for a pet. One day I found a baby bird hopping around the garden, unable to fly. I kept it in a box hoping it would be my pet that I was desperate for, only I didn’t know about feeding it properly or how to care for it correctly. I kept it secret so didn’t check on it as much as I should have as I didn’t want my parents to find out. I did feed and water it but not the right things. I’m not sure if its parent would have been still caring for it. Obviously it died.
I frequently think of that bird and what I did to it 😢 I’ve done many bad things but that one’s particularly horrible.

I’m sure the bird has forgiven you up past the Rainbow Bridge. You were only a baby yourself. Flowers

Funnily enough, I've been thinking lately about some of the things I did when I was younger and they don't reflect very well on me at all. Ultimately I only have myself to blame but I do wish I had been given more attention and moral guidance when I was growing up.

What kind of guidance do you think you needed? I’m only asking because I have myself down some shameful things in my past that still haunt me and know k have a daughter myself to want to guide her as best as I can into knowing how to react or not be peer pressured into doing something.

Aged 16 lied about having a terminal illness. Took it too far. Hurt a lot of people. I was being abused by someone who told me nobody would miss me if I died and stupidly I wanted to test the theory out without obviously dying and in my immature mind it was the only way. It was awful and I got in severe trouble

You must have been in a really bad place to have done that and I can imagine when it all came out you must have felt horrendous. I hope you’re doing better now xx

KeeleyJ · 20/04/2026 17:29

This wasn't me but i didn't discourage it either...

Computers were a new thing when I was at school - total of about 5 computers for the whole year.

Everyone was allocated a computer terminal, I was e.g computer number 3 and roughly 8 people were to share the same one that year. No logins or passwords, just a folder each for us to save Higher English essays on.

Coincidentally I used the same one as the nastiest bully in the whole school. (Verbal and physical violence, even put her own Mother in hospital).

'Someone' accidentally deleted all of her essays just at the point she was due to submit her stuff to the exam board.

That’s brutal. Way worse than having an affair or pooing outside!

VimesandhisCardboardBoots · 20/04/2026 22:56

I stopped DP from singing.

DP has an awful voice. Actually, that's not really true. DP has a perfectly nice voice, she's just utterly tone deaf. I used to quite often hear her singing to herself and think "That's quite nice", and then ask her what it was and it'd be some song that I know, but there's no way I'd have recognised it from what she was singing. The tempo is wrong, the notes are wrong, the words are often wrong too. If she's singing along to something, or along with other people, then oh god it's painful, she can make a room of people all fail to sing Happy Birthday because they're all trying to somehow get in sync with her. Basically, there's something in between her brain and her voice that is just utterly broken.

And this intrigued me. I like weird brain stuff. I've got aphantasia and face blindness and its so weird knowing that everyone has this superpower that I don't, and that I and most of humanity have one that DP just doesn't have. So I'd talk about it lots, it made me laugh in the same way it makes DP laugh when I desperately struggle to work out who I'm talking to, only to realise half an hour later it was my Step brother. I'd gleefully tell people about DPs singing. It wasn't mean, at least it wasn't meant to be. I loved her, and part of what I loved about her is this utter inability to do something that to me seemed so basic.

And then one day we were in the car and a song DP loves came on the radio. And I realised DP wasn't singing along to it. And then I realised I hadn't heard her sing anything in months.

"You don't sing any more."
"No, I don't"

We sat in silence for a minute, while the sheer horribleness of what I'd done sunk in, and then the apologies started. I must have gone on for 15 minutes or so, apologising profusely, telling her how bad I felt, how I never wanted her to stop singing, begging her to not stop on account of me.

And she accepted my apology. But she didn't start singing again. That was a decade ago, and it's only been in the last 6 months or so that I've caught her singing. At first when she thought noone could hear her, and more recently when we've been in the car together. I've not said a word. I don't dare, in case it stops her again.

We have a wonderful relationship. I adore her, and she claims to adore me. We have the sort of relationship I'd be intensely jealous of if I wasn't in it. But I will always be the man who stopped DP from singing, and thats something I will never forgive myself for.

I was young, and would never do it again.

The “normal” taking drugs (coke a whole load of coke)

But the most guilt is arguments, I didn't tend to start them but holy shit I finished them…straight for the jugular every time, if I knew it would hurt I would say it, and there was no level of hell too deep.
