@ChickenBurgers and @Thejoyfulstar both of you sound like you might have inattentive ADHD. I think there are an awful lot of women in particular who are undiagnosed with it. You may not have it so severely that you need medication but it might help you to read about it and understand why you are the way you are.
I suspect I have it and have many of the traits you describe. I was so hard on myself for decades but now understand why I am not as efficient as some other people and struggle to get things started, organise myself, get places on time etc. I also have hyper focus and get very motivated to an excessive degree about things that I'm really interested in. Meanwhile I get overwhelmed and overstimulated in noisy environments, when there's excessive visual or auditory stimulation. So I find it difficult to know where to start to clear clutter, but find clutter overwhelming - catch 22!
If these things sound familiar to you, you might want to read up about it. It's been a revelation to me and I now understand myself and am much kinder to myself. I have developed strategies that really help me, and that NT people probably do naturally, like leave things the night before by the front door so I don't forget things; plan backwards how much time I need to get somewhere so I'm not late; set my alarm for ten minutes when I have to sort something out so I can do it over several days and don't feel overwhelmed by it; always look behind me when I leave a train, cafe etc so I don't lose things; ask people to slow down when given instructions or directions as I can't follow multiple instructions (another ADHD trait).
There are lots of resources now to help: YouTube videos, Facebook groups, books etc. It's really hard to get a diagnosis as an adult as the NHS doesn't want to spend the resources on it but just knowing that there's a reason you're the way you are is revelatory. Just understanding myself actually helped me to be kinder to myself and paradoxically get more done! Also I found a job that's self employed and so I can both work but set my own timetable and don't get so burnt out and have plenty of rest in between, working at night if I need to to spread out the load.
