SHE LEAVES GAS ON REPEATEDLY FOR YEARS

So she's not a teacher then? She can't be both a couch hog and a teacher. And if this started when she was 30 and has been going on for decades how the hell old is she now?
None of this makes sense.

ADHD would not, on its own make you unable to teach. Source: I personally know several teachers who have been diagnosed with ADHD.

It’s poorly written.

My PDA Audhd young person hates listening to solutions or “being told what to do”., by the way. Because they lack interoception and insight.

Not responding the way you think she should respond could be a part of her overall personality and condition.

It sounds like she has some executive functioning problems. She forgets to finish tasks and loses things constantly.

At work she might have scaffolding to help her - teaching is something which can be both inherently structured (working to a lesson plan) and improvisation, reacting in the moment. So if she has challenges with starting, transitioning between, or completing tasks, this could be masked at work by other features of the environment. There is something called "body doubling" being researched now, (which basically means doing stuff together with other people). Turns out doing things in routine with other humans (like you might do in a school) can help those with executive functioning issues to manage. So she might have found a career that allows her to use her jumping-about-quick-thinking-brain and supports her scatty-forgetful-brain.

Or SHE could mask heavily at work so when she comes home there is nothing in the tank for organising self care, cooking and so on. If she is undiagnosed neurodivergent then she may be living with profound exhaustion that even she is not aware of.

What causes this- well it's probably some mix of adhd and maybe autism or traits in those directions. It could be depression that she is battling through day by day. It could be PTSD from some trauma she had that you are not aware of.

The thing is, what should matter to you is what help does she need, is she aware that she maybe needs more to support her at home than she has in place? What is her attitude to neurodivergence, is she aware of others in the family with similar things going on? How would you know what her views are, too - she might be going through a process of diagnosis or treatment without telling you, for all you know.

Your OP is more of a tone of frustration "What's WRONG with her??!" and to help her you need to be more supportive, curious and less judgmental.

I do this with the gas oven and hair straighteners. I’m not an alcoholic, on drugs or an idiot. Im dyslexic and think I have other issues, maybe ADD, but at 60 can’t be bothered to find out. My memory is atrocious and always has been.

So Ive changed to an induction hob and hair straighteners that switch themselves off if left on for too long. They’ve been a life changer.

I now just have to sort the other numerous things I get wrong every day. 🤔

I think I know what this is. Are they by any chance a teacher?

I would contact your local Fire Service for advice.

Someone in my family had this kind of behaviour and I was confused for years until I discovered that they were secretly drinking.

This or abusing drugs

I am obviously not the sharpest tool in the box 😂

Can you talk to her family and find out if she was like this as a child/teen?

You are naturally focused on the dangerous things she is doing but have you noticed her leaving other things forgotten that aren’t dangerous?

Does she forget to lock her car or the house, lose objects, or miss appointments?

I’ve known a couple of people like this. One left her hair straighteners on overnight. Another was just … careless. She didn’t have any conditions that contributed to it, she was just careless and thoughtless. She set fire to an electrical kettle by putting it on the stove, wrecked a steamer I had by cooking rice in the water part, would cook and then leave pans / plates / cutlery for days. She would take cups of tea up to her bedroom but then, when we went to find some mugs, they would be there covered in green mould. She would wreck other people’s stuff and her own and then say that she didn’t care about “stuff”. But she’d never been taught to look after her stuff.

but I asked someone with adhd and on adhd forum they said it’s not this bad

Do you honestly believe people with ADHD are all the same??

I completely agree.

I don’t understand why some are being deliberately obtuse, as all it does it make them look stupid for not understanding.

OPs thread is easy to understand.

If they’re confused then why not just ask a question sincerely, instead of trying to bully OP because they’ve got nothing better to do with their lives.

Solutions for the teacher? She isn’t going to listen to OPs bright ideas

Some posters appear to be trying to be deliberately obtuse, pretending they don’t know what the OP means, presumably because of the way the post is written. I hate it when MN is like this.
Of course it could be written by AI, and yes, that’s annoying, but sometimes a poster may not be using English as their first language.

Are they pissed?

Recently?! That show started in 1987!

Why do you keep mentioning they're a teacher?

If you're genuinely concerned you should take them to a doctor. If a child is within the home you should report them to social services.
