First of all, well done for seeking support. It’s scary to open up about feeling like this.
My story - like you, ‘high flyer’ at school, labelled G&T but sometimes I’d do well, sometimes I’d totally miss the mark. The further up the education ladder I went, the more difficult it became, especially when I got to uni and had to manage life and finances on my own. Failed one uni course. Managed to pass the next. Diagnosed with depression at about 20 but I see in retrospect it was ND burnout.
Always found work difficult. I did shifts and I turned up on days off, slept in when I thought I was on a late shift and I was on an early!
I realised from a MN thread I might autistic. Hyper focused on the idea and ended up requesting an NHS assessment and got diagnosed aged about 34. It was validating but at the time, there was no support. It was ‘Here’s your diagnosis report, here’s a charity website link (that’s impossible to navigate), off you go’. I found more support from MN. Years later I realised I probably had ADHD. Procrastinated for ages in case they thought I just wanted meds to make me feel better! Finally got an assessment and diagnosed at 41. I did start meds. They have made the world of difference to me! I can function better. I’m more on top of things. I can keep track at work. I can complete tasks. I take a higher dose the week of my PMS and it eases the symptoms.
There is absolutely good reason to get diagnosed as an adult. Better understanding of yourself is so validating and yes, if you can take them, meds help. I would say to avoid Harrow Health. I’ve heard the assessments are extremely variable and lots of complaints.
Things that have helped me: meds (of course), magnesium and omega 3 supplements. ADHD coaching (helped me recognise my strengths and find strategies around my time management). Also body doubling. You can do it with an individual but there is an app called dubbii. There’s step by step guided ‘how to’ videos about how to do everyday tasks. Also there are live, hosted sessions for an hour every 3 hours. Everyone is just getting on with tasks but honestly having the support is amazing! I get so much done when I’m there. It’s about being of a like-minded community. Definitely worth checking out.
So yes, for me, getting diagnosed as an adult has validated my life experience. Meds have helped a lot, as well as ADHD specific coaching. It’s worth looking at Right to chose in your area. Good luck! If you join dubbii, I’m known by another name (a play on my MN one!).
