Somehow this has turned into an essay, apologies, but here goes... I found the framework of school very difficult at that age - exam pressure and struggling with what I now know is ADHD, and seeing no way out. However, gradually gaining more control over my life after I left school has been very good, although it took me a long time to realise I had control!
I've always taken things at my own pace and not necessarily done things in the same order or at the same speed as my peers and that's worked for me. Ie, I did go to uni eventually, but at 21 instead of 18 as I was burned out from education.
In my late 20s, I worked freelance in a professional role that attracts a lot of ND people. I met quite a few people who had autistic traits and didn't like the 9-5 office framework, so enjoyed making a living freelancing, of all different ages.
There's so much more room for individuality as you get older, and styles of socialising change so much - I found when I was younger it was very much 'we must all drink alcopops and go to the same terrible club every week while wearing the correct clubbing attire' (not sure what the gen z version of this is!).
Not sure if your daughter has strong interests but I've loved having my own money and being able to indulge mine a little bit.
And learning more about what works for you is definitely helpful in terms of coping strategies.
Writing this, I've realised that I go through very black stages of being depressed and stuck and thinking everything is impossible, to everything suddenly accelerating, happening at one and turning out fine. Not always perfect, but good enough (for me, maybe at the point when I'm forced to stop mulling things over and take action). Thinking about this, have had this with GCSEs, A levels, some of degree, job stuff, some social stuff, other stuff.
Anyway, I'm 34 and now sat in my nice home working space, doing a good professional job which is very well suited to neurodiverse people. My boss is super-logical, very direct (possibly also ND?) and good at his job, so I'm valued for doing my role well, and have had two pay rises and hopefully about to get a promotion since starting a year and a half ago. (Not saying this to sound obnoxious, just highlighting that I've landed in a good working environment that is suited to me).
I'm waiting for my first house to go through and looking forward to moving to a new area and using my slight obsessiveness to decorate it perfectly!
