I was diagnosed in February last year, and your post definitely rings bells with me.
Focusing on and finishing tasks - sometimes I feel like I’m having to physically wrestle my brain into looking at my computer screen. Have you looked up ADHD task paralysis?
School/uni - yep. I was bright, but would get told ‘you just need to apply yourself’ etc. I was always doing homework in the 20 minute form period before actual classes. Always had my nose in a book, to the point that you could literally shout at me from across a room and I wouldn’t hear you, but would do anything other than revise for exams. GCSEs were acceptable, but by a-levels, I was slipping, and then made it to final year of uni before dropping out without completing my dissertation.
Work - I got fired from my very first ever job. Started off well and then… I’m not sure really what happened (I was only 13 or so - long time ago haha). Every job since then I’ve left, in part, because I’ve been convinced that I’ll get fired if I stay. One formal disciplinary and a few informal bollockings, generally because I got overwhelmed and let everything pile up. The imposter syndrome is intense!
Life admin - I actually quite like opening post. But constantly getting estimated gas/electric bills because I don’t get around to giving meter readings. Or racking up library fines because I’d not get around to returning books. Not cancelling subscriptions… I could go on lol.
friends - I have a couple of friends from a previous workplace and we meet up once very few months. But they would probably count as my ’best friends’ and I’m really conscious that I’m not theirs. There’s no one I can message and say hey, do you want to go for a drink after work, or similar? I do meet-ups etc, but actually forming connections? That’s hard.
Binge eating - oh I’m sooooo bad at at this! Although on this I have actually improved over the last 2/3 years. I’ve found it helpful to use a PT once a week - I have to go otherwise I let him down, and then I have to do the gym classes, and then I find it easier to eat healthy… the PT session helps me sustain a more positive cycle. It’s of course not affordable for everyone but might be worth a go?
Growing up and being constantly told you’re not trying hard enough, to stop being lazy… it’s traumatising, in a very literal sense. I was (am) socially awkward, anxious, can be depressed. Before I was diagnosed I had basically concluded I was a little incompetent at life in general. It’s really shit!
But in some ways it’s kinda cool - if nothing else it makes you resilient, we think a little differently to other people, which means we can be fun and quirky, we make great friends, not to mention being really valuable to employers who understand how to support us.
Tl;dr - you’re not on your own! Get on the list for dx if you’re not already, and in the meantime look for support groups in your local area? There are also a ton of nd people on social media you can follow with advice that actually stands a chance of being helpful.
good luck xx
